Libeler (OP) has default trust T2, libeler's victim (me) was wiped from T2=injustice done.

You are both in the default trust network at depth 2.
1062  Economy / Service Announcements / Re: [ANN] Joinmarket - Coinjoin that people will actually use on: May 16, 2015, 06:02:46 PM
Good to see that some progress is being made on usable CoinJoin. This seems like the best CoinJoin project around currently.

Some possible ideas/improvements come to mind:
- Tor should be easier to use. Probably the default configuration should be to use Tor.
- Only Tor-friendly IRC servers should be used, and only over TLS.
- To reduce centralization, multiple IRC servers could be used. Makers would idle on all of the servers, and takers would find partners using multiple randomly-selected IRC servers. If any servers are down, Joinmarket should issue a warning, as this may be a DoS attack on the IRC server designed to funnel people to attacker-controlled servers.
- Instead of requiring NickServ registration, makers could generate an identity separately (maybe just a Bitcoin address) and communicate it on the IRC channel using public-key crypto. This is more convenient and will work across multiple IRC servers.
- In exchange for a (comparatively large) extra fee, takers could require that the unspent-outputs provided by makers be x blocks deep (I'm thinking ~1500). This reduces the Sybil risk because an attacker will only have so many bitcoins, and this requirement ties up a lot of their bitcoins for a while if a lot of takers are routinely requiring that at least some of their partners provide old bitcoins.

1064  Other / Meta / Re: How can a hero account only have 99 posts? on: May 13, 2015, 01:55:33 AM
IIRC only Newbie, Hero, and Legendary members don't get demoted normally. Maybe I'll fix it at some point, but it's not really a big deal.
1065  Other / Meta / Re: Requesting Posts be undeleted and unedited from Several Scammer Accounts on: May 11, 2015, 04:53:15 PM
You request is too broad/complicated. I can't do most of that stuff automatically.

Give me a list of topics and I'll restore posts by those users that used to be in those topics.

After I restore the posts, give me a (preferably short) list of posts that you want the edit logs for. I can't unedit posts automatically.
1066  Economy / Auctions / Advertise on this forum - Round 150 on: May 11, 2015, 12:22:01 AM
The forum sells ad space in the area beneath the first post of every topic page. About 25% of ad income goes to the forum moderators as thanks for all of their work. (There are many moderators, so each moderator gets only a small amount -- moderators should be seen as volunteers, not employees.) The rest is stored in the forum's treasury (verifiably), where it sits until the forum needs it.

Ads are allowed to contain any non-annoying HTML/CSS style. No images, JavaScript, or animation. Ads must appear 3 or fewer lines tall in my browser (Firefox, 900px wide). Ad text may not contain lies, misrepresentation, or inappropriate language. Ads may not link directly to any NSFW page. Ads may be rejected for other reasons, and I may remove ads even after they are accepted.

There are 10 total ad slots which are randomly rotated. So one ad slot has a one in ten chance of appearing. Eight of the slots are for sale here. Ads appear only on topic pages with more than one post, and only for people using the default theme.

The ad lasts at least 7 days starting from when I put it up. (However, if you look at the ad history you'll see that ads usually get at least 8 days, and sometimes as many as 10, but this is random and definitely not guaranteed.)

Stats

Exact historical impression counts per slot:
https://bitcointalk.org/adrotate.php?adstats

Info about the current ad slots:
https://bitcointalk.org/adrotate.php?adinfo

Ad blocking

Hero/Legendary members, Donators, VIPs, and moderators have the ability to disable ads. I don't expect many people to use this option. These people don't increase the impression stats for your ads.

I try to bypass Adblock Plus filters as much as possible, though this is not guaranteed. It is difficult or impossible for ABP filters to block the ad space itself without blocking posts. However, filters can match against the URLs in your links, your CSS classes and style attributes, and the HTML structure of your ads.

To prevent matches against URLs: I have some JavaScript which fixes links blocked by ABP. You must tell me if you want this for your ads. When someone with ABP and JavaScript enabled views your ads, your links are changed to a special randomized bitcointalk.org URL which redirects to your site when visited. People without ABP are unaffected, even if they don't have JavaScript enabled. The downsides are:
- ABP users will see the redirection link when they hover over the link, even if they disable ABP for the forum.
- Getting referral stats might become even more difficult.
- Some users might get a warning when redirecting from https to http.

To prevent matching on CSS classes/styles: Don't use inline CSS. I can give your ad a CSS class that is randomized on each pageload, but you must request this.

To prevent matching against your HTML structure: Use only one <a> and no other tags if possible. If your ads get blocked because of matching done on something inside of your ad, you are responsible for noticing this and giving me new ad HTML.

Designing ads

Make sure that your ads look good when you download and edit this test page:
https://bitcointalk.org/ad_test.html
Also read the comments in that file.

I will send you more detailed styling rules if you win slots in this auction (or upon request).

Auction rules

You must be at least a Jr Member to bid. If you are not a Jr Member and you really want to bid, you should PM me first. Tell me in the PM what you're going to advertise. You might be required to pay some amount in advance. Everyone else: Please quickly PM newbies who try to bid here to warn them against impersonation scammers.

Post your bids in this thread. Prices must be stated in BTC per slot. You must state the maximum number of slots you want. When the auction ends, the highest bidders will have their slots filled until all eight slots are filled.

So if someone bids for 8 slots @ 5 BTC and this is the highest bid, then he'll get all 8 slots. If the two highest bids are 8 slots @ 4 BTC and 1 slot @ 5 BTC, then the first person will get 7 slots and the second person will get 1 slot.

The notation "2 @ 5" means 2 slots for 5 BTC each. Not 2 slots for 5 BTC total.

- When you post a bid, the bids in your previous posts are considered to be automatically canceled. You can put multiple bids in one post, however.
- All bid prices must be evenly divisible by 0.05.
- The bidding starts at 0.50.
- I will end the auction at an arbitrary time no more than 12 days from now. (I will probably end the auction 1-3 days before the ads are scheduled to go up.)
- If two people bid at the same price, the person who bid first will have his slots filled first.
- Bids are considered invalid and will be ignored if they do not specify both a price and a max quantity, or if they could not possibly win any slots

If these rules are confusing, look at some of the past forum ad auctions to see how it's done.

I reserve the right to reject bids, even days after the bid is made.

You must pay for your slots within 24 hours of receiving the payment address. Otherwise your slots may be sold to someone else, and I might even give you a negative trust rating. I will send you the payment information via forum PM from this account ("theymos", user ID 35) after announcing the auction results in this thread. You might receive false payment information from scammers pretending to be me. They might even have somewhat similar usernames. Be careful.

Terribly sorry for the very over-long auction -- I completely lost track of time due to end-of-semester university stuff.

Final result:

1068  Other / Meta / Re: Why can't this forum be a "trusted" community? on: May 06, 2015, 07:59:56 PM
The forum itself isn't going to mark anyone as trusted. That's for traders to decide individually.

It is possible to get trustworthy enough that most people won't require escrow. Escrow agents themselves must meet this criteria, since you're trusting them with the money (unless you're using multisig). But this requires a lot of trust because you have to trust that:
- The person isn't executing a long con.
- In case of an unexpected dispute (lost in the mail, etc.), they will handle it fairly.
- They're competent enough that you can be sure that their account isn't compromised.
- Etc.
1069  Other / Meta / Re: How does the archival board work? on: May 05, 2015, 12:53:05 AM
Old threads don't need to be moved to Archival. Just lock them. Archival is meant to be used by moderators in only a few rare situations. (Though I don't mind if you move your obsolete topics there if you want to for some reason.)

FYI to everyone in this thread, I was so happy to "win" my bitcointalk ad, I didn't check the username close enough before getting scammed for 3.6 btc:

Sorry for your loss. To hopefully make future cases of this sort of thing more difficult, I added a warning to all PMs by newbies.
1071  Other / Meta / Newbie PM warning on: May 01, 2015, 01:03:51 AM
PMs from newbies now have a warning added to the beginning of the PM. The warning is actually added to the PM's text, so it won't be added to old PMs or removed when the sender leaves newbie status.

The warning is:
!!! WARNING: This user is a newbie. If you are expecting a message from a more veteran member, then this is an imposter !!!
1072  Bitcoin / Bitcoin Discussion / Re: Has the NSA already broken bitcoin? on: April 27, 2015, 11:46:37 PM
OK, if you were in control of the hashing algorithm used by Bitcoin, which one would you use and why?
An algo designed by Bitcoin Engineering Task Force specifically for bitcoin. Then and only then bitcoin has a chance to be safe. Bitcoin should not use hashing algo because it is recommended by NIST or NSA or whatever. On the contrary, other organizations should use whatever bitcoin network uses because if it is broken bitcoin will act as honey-pot and will inevitably expose the weakness!

The "Bitcoin Engineering Task Force" (aka Satoshi) already decided that SHA-256d is the best hash algorithm for Bitcoin. Wink

SHA-256 is very strong.  It's not like the incremental step from MD5 to SHA1.  It can last several decades unless there's some massive breakthrough attack.

Designing strong crypto is really really hard. Of the 56 algorithms in the SHA-3 competition (submitted by world-class cryptographers), some sort of potential weakness was found in ~33 of them. It's best to settle on a few algorithms that the academic community can scrutinize carefully for many years, as they've been doing with SHA-2. Even rather paranoid cryptographers like Bruce Schneier aren't really concerned about SHA-2. No one has any serious ideas on how you would even start to attack it. The similar but far-less-secure SHA-1 isn't even considered to be absolutely broken yet -- there aren't yet any examples of SHA-1 collisions, for example.
1073  Other / Meta / Re: Contribute To Bitcoin Economy... on: April 26, 2015, 08:39:46 PM
In addition to the enforcement issue: From time to time people have asked me whether they could sell their accounts or use them as collateral because they have an emergency need for money or have come on hard times. I'm not going to tell them they can't do this. It's your account and you can do what you want with it. I find it pretty distasteful (it's like selling your identity), but the act of selling your account does not itself hurt anyone else, and in fact scams via account sales are very rare.
1074  Other / Meta / Re: Quickseller Gave me a negative trust Without Considering possibilities on: April 25, 2015, 03:55:57 PM
As long as BadBear trusts him nothing can be done.

Not true. If 2 other people on the default trust list exclude him, then he will no longer be in the default trust network.
1075  Other / Meta / Re: personal messages question on: April 22, 2015, 07:51:44 PM
That code snippet has to do with deleted posts, not PMs.

PMs are deleted from the database when the sender and all recipients delete it. If this doesn't happen, then it's not deleted. There is no expiration. PMs can also end up stored long-term in the forum's periodic database backups.

On this forum, topics and replies are never truly deleted, and edits are also logged.
1076  Other / Meta / Re: DDoS on: April 22, 2015, 04:39:07 AM
Since I mentioned Cloudflare in the OP, I thought I'd note this here: I just learned that Cloudflare's "keyless SSL" feature still allows them to undetectably MITM all traffic. How it apparently works is that you keep the HTTPS key, but session keys are generated in a special way that allows both you and Cloudflare to decrypt the HTTPS traffic. Pretty sneaky, and not at all widely known. My suspicions that Cloudflare exists to spy on encrypted Internet traffic continue to rise.
1077  Other / Meta / Re: Do not post SSNs, etc. on: April 22, 2015, 04:19:04 AM
The idea of "illegal data" is indeed very ridiculous for a variety of reasons.

I believe that it is not actually strictly illegal for bitcointalk.org to allow people to post SSNs (though it may be illegal for the poster in some circumstances). It's probably also not illegal for me to allow users to post death threats, or links to Silk Road-type sites, or detailed instructions on how best to kidnap someone. But even though these aren't illegal for bitcointalk.org, defending these activities (especially to ISPs and other service providers) is too difficult/expensive to really justify.

If you need to use someone SSN etc. in order to prove that they were scamming or to link some scamming to them as an individual, then I will probably go out of my way to allow this. But if their identity and crimes are already well-known, then it's not worth the trouble.
1078  Other / Meta / Do not post SSNs, etc. on: April 21, 2015, 09:37:39 PM
For legal reasons, any sort of secret ID code/number that is used by the insecure legacy government/banking systems is banned from bitcointalk.org.

This includes, for example:
- US social security numbers
- Non-US government ID numbers that can cause security problems when released
- Credit card numbers

Exceptions might possibly be made if this info is absolutely essential to a scam investigation or it's very certain that you're posting secret ID codes that belong to you.

It shows all recent posts by newbies. Posts new to the patrol page for you have a "new" icon. It's intended for patrolling for spam.
