From what I read I don't think this thread is quite as mean-spirited as that one.
That may be because thorstach doesn't appear to be a serious poster actually engaging in financially destructive short trades. I think he/she is a comedy sock puppet account for another forum member.
Mrpercentage also said the market was crashing, but he was independently a participant in the rest of the forum, he openly discussed the faulty reasoning behind his beliefs, and he offered specific trades he was making. Thorstach doesn't seem to exist, except to show up on the worst day of the month and say "the top is in."
I would viciously tear into thorstach too, except it's all apparently in good fun. Because the top is in.
