Ignore them. Seriously.
The people who care the most about BS&T create terms like "Team Ponzi" and insult other members for withdrawing or blame the end of BS&T on single members.
The entire forum, however, is made up members that, quite frankly, don't care about BS&T.
I think, scarily enough, you may be underestimating how many people invested in BS&T. I reckon that before Pirate closed it down it had pretty much reached saturation - that is to say, pretty much everyone that was willing to consider investing money in BS&T had put money in, and greed being what it is lots of people were willing.
