People should be allowed the rights to self-moderate their own forums.
Instead of private invite-only forums - everyone should have "read-access" to everything posted on ET, but thread starter should be given the right to moderate his own forum by taking away "write-access" from the people who create trouble on his thread. To be able to bar anyone from being given write-access on a particular thread, thread starter must gain some kind of acceptability from other readers. My suggestion is follows:
Implement following small little box that will be present on top of each thread. The box will have the space for thread starter to propose the name of the miscreant from whom he wants to take-away the "write-access" for this particular thread. People should be able to vote in favor Vs against the proposal.
vote to ban "this guy" from this thread - kind of small window on top of each thread. I will say if 75% or more people vote to ban the guy, the thread starter should have the ability to ban the guy. Minimum number of votes required should be at least 10, this will ensure that just 3 guys don't collude together to ban a person from a particular thread.
Threads like "Characteristics of a Successful Trader" are very useful thread for majority of people. If some miscreant will start making trouble, hordes of silent majority will come and vote to ban this person and so the problem that EricP faced will be alleviated.
+1 to thread starter being able to moderate their own threads.
