Hello! Trolls are very common around Wikia, so here's a few tips to keep you safe:
Do not feed the trolls, as they will make them worse. Imagine a troll. Now imagine one a hundred TIMES more worse! That will really hurt you and your feelings wouldn't it? So don't feed them.
Before letting an admin know on this noticeboard, please consider warning the troll. With a bit of luck, this should resolve the problem.
Don't be shy to put your issues up on the admin noticeboard! It can be really helpful, and for every notice we get, we investigate the user(s) and try to resolve the issue. Better safe than sorry!
That's it! Stay safe!
