I don't think I am never going to leave this forum no matter what. What about you ? Can there be anything (assuming you did not break any of the rules) that will make you leave the forum or not?
No offense, but I find it strange that you would bear anything that possibly could go bad & wrong and still accept it and stay. Question is of course, could things here in the many places of the forum go so bad, that it would be a real pain in the ass to cope with it, maybe for a long time, maybe forever? I don't know, I have no magic crystal bowl or Palantir. I have some faith in the current administrators and moderators that they do a good enough job to keep it as it is or make the forum every day a little better place. At this size of a forum and user base, that's not an easy task.
If hordes of trolls or destructive weirdos start to marode in and over this forum, beyond control, I might leave for some time if fighting the ground becomes too tedious. I don't enjoy destruction, offenses, flame wars, endless trolling.
I certainly will lurk in from time to time, to check if air got breathable again, as I like this forum a lot, too. As it is now, I wouldn't want to leave either, but I'm not that absolute to accept anything here. I have certain principles and lines that shall not be crossed too often. And if I can't defend my lines anymore, it'll be time to move on.
