They've been buying into the 1000s haven't they? God they must be taking massive losses. Wouldn't be surprised if they're the ones with these fake walls trying to inflate the depths for quick dumps.
They solicit coin off-exchange too. I have an account set up for 25 bitcion minimum sale and purchase with one of their VPs. I read somewhere the rumor that they solicit bitcoin from BitPay, whose bitcoin-accepting vendors may immediately sell bitcoin for dollars.
