The solution is not to throw more moderation at the growing mountain of "Now-I'm-gonna-be-rich-too"-type newbies crying over losing the buck fifty they made mowing the lawn. The solution is to move altcoins altogether from this bitcoin forum to another forum. One could call it specialcointalk.org. You know, like in "special coins for special people"
That would be a permanent solution. Altcoins can give some really bad PR to bitcointalk due to the huge volume of scams that I've seen in the last days.
Of course it's always newbies fault to avoid using a trusted escrow and sometimes it is an expensive lesson
