Allow me just to say, having been a part of forums of a different topic for about 10 years, and running one right now, there will ALWAYS BE A REVOLVING DOOR OF TROLLS, no matter how hard you try to not have them. I didn't read all umpteen pages of this thread so I don't know who the culprit is and I'm not taking anyone's side. I am saying that, it's like magic, the computer let's people act out parts of their personality they don't get to act out in real life, and many times that is unfortunately their aggressive "tough guy" side or their "better than thou" side.
And just when you think one or 2 trolls are gone and taken care of, make no mistake, there will be 1 or 2 more to pop up. I promise. Just don't define the value of your life by what happens on a computer message board. Instead use it all as entertainment. I have been the victim of trolling too, and make no mistake, I make it really fun for myself, with my counter troll abilities to the point that the Troll usually gives up and leaves embarrassed with the cursory, "Screw you. This whole forum sucks! I don't need you losers." then they are gone..
But that happens because I have fun with it rather than getting all hurt emotionally by what some person on the other end of a keyboard who has NO IDEA who I am says...
Just my 2 sense...
