Although I completely sympathize with the OP, working through the garbage sometimes is no different than working through "noise" in the markets. You simply wait for the best setups (message threads), and then get involved in those (place a trade).
I have myself used the complain button in the past whenever a member swore at me or was vulgar, and I found that action was swift and the posts cleaned up. If there is a thread someone doesn't like, simply stop reading it. If you find nothing useful to read, then you have more time to do something else. It usually takes two people to have a shouting match, so if you stop replying to their messages, its usually problem solved. I know that many times that I've said the same thing over and over again its because I wanted to be right.... I wanted to convince the other person to see it my way. What a silly goal.
Trolls only operate because they are fed posts to feed off of, so not replying to them is a wonderful and easy tactic. I've been called a troll a few times, and although I of course don't agree with this label, that poster is free to label me as such and we can both go our own separate ways.
What's wonderful about ET is that everyone is given a voice. I much more prefer less moderation and more hunting on my part for something good, rather than a message board that seems completely free of any bickering, which would make me wonder about heavy moderation and hidden agenda.
To the OP, why not start a journal and show us your trades since you have something good now? Lord knows what what we need more of around here is actual trading discussion, and there is no better way to bring about the change you seek than by leading by example.
