You have to understand 95 percent of the time people are going to side with the troll as pony has. Not because the troll is necessarily right, but because they don't bother to look into the history of the events leading up to what is currently going on now. I can see where if you are in fact being stalked, it can suck and it isn't by any means your fault for replying, I've been guilty of this myself on other forums, if someone is following you on every thread you touch, that is not your fault and that is not you hijacking the thread, that is simply a troll being a troll. Now I don't know thedoc or pony or many users for that matter, I know just a very little, this isn't the primary forum I tend to go to for the same reason this user is now leaving and for the reason that most of the non trollers on this site will side with the trolls. So i couldn't say thedoc is wrong because I don't know him nor you, but if what you say is true I would suggest you just hit up a mod and ask what measures can be taken to avoid this conflict, maybe they will send thedoc a message or something? I don't know what to tell you man, your in a shitty situation because of the users around you feel it is better to back down to trolls then face them and I know how that can suck and the user that is leaving this forum feels for you too, that's why he's leaving.
