Here's what has happened so far:

Recap: Withdrawl attempts from bitjack21.com have gone unpaid for almost a week.  No responses to e-mails, PM's, and one post of "I'm confused, who needs what now?" by Andrew Bitcoiner in the bitjack21 thread.  Total withdrawl attempt was over 133 btc. If any of the mods need more evidence, I can produce it.  I took screenshots of the e-mails, withdrawl screen, etc. in the off chance that something like this would happen.  Bottom line: Don't deposit anything at bitjack21.com, you won't be able to withdraw anything.

EDIT: Payouts have been happening, potentially not a scammer

EDIT AGAIN: He deleted my bitjack21.com account which had over 260btc left in it.  No communication, I was going to sell my account to hedge against him not paying out at all and he deleted it.
