It took 10 days for the rally to start after the Silk Road crash

Imagine this happening 6 months ago. How the price would rise.
Now everybody is like who cares. We're waiting for anything slightly negative so we can totally panic. 

10's of thousands of people, every single day, being given the option to pay in bitcoin.

Not only this..but sellers are going to get them to start paying out in bitcoin. This is huge and it will force the hand of other outsourcing sites.

This right here will show the advantages of bitcoin over paypal as the entire world becomes available

Anyone use itBit?  Decent exchange out of Singapore with fairly sizable seed money.  Anyway, they came out with a PR basically saying Mt Gox full of shit (in nicer words of course!)

so a question arises: what if mtgox was right, and bitcoin foundation was wrong saying that bitcoin protocol is ok?

I give this scenario a 1:10000 odds at best. But if it is true, then prepare for a shitstorm.

Guys. Just think. I'm getting most of my transactions "malleated" right now, so what? The original transactions never confirm, but the "malleated" ones do and they are registered correctly by Bitcoin-QT. You just see all your transactions twice, one is confirmed and the other will never be, so what? Balance is displayed correctly by QT because the standard implementation handles correctly malleated transactions.

Its just a visual annoyance, as now unconfirmed/doubled transaction pile up on the UI, but apart from that visual annoyance nothing is happening.

Try yourself. Send a couple of transactions and you will see.

What could be the motivations of whoever is doing this? 

To exploit an MtGOX-like bug on any exchange or system that may happen to have such a bug?

SELL!!!

[ShroomsKit]

Looks like the sheep are getting ready. Any time now.

[kehtolo]

I'm not sure who could be behind this, but it is obviously someone who doesn't like bitcoin, and wants to scare people off.

There is also a large scale spamming of the blockchain going on.

This is someone with (i would guess) considerable resources.

Or like suggested above, trying to cause another drop to scoop up more cheap coins.

HODL!!!!

[wachtwoord]

Oh wow! Fiverr accepts Bitcoin! That's very nice news.
You can start panic selling now.

Never heard of the service. Can sellers be paid out in Bitcoin as well?

There's no "exploit" unless you use a custom software that uses "transaction ID's" as the only element to check transaction, and then you let someone to "social engineer" you by making you believe they never received the money you sent them.

If you use the reference implementation (bitcoind/Bitcoin-QT) your wallet will show BOTH transactions (the "malleated" and the original one) and will display the CORRECT balance, so there is really no way for you to be social engineered. If you use a custom implementation that only cares about txid, then probably the "malleated" transaction won't show up in your client/accounting system, leaving the door open to a social engineering attack.

TL;DR: whoever is trying to "malleate" as many transactions as possible is doing it either for shit and giggles, either for trying to spread some panic among novices and thus induce panic selling.
