Before I was made admin on EU I was always being griefed by others for no reason and having to make ban threads, EU really does need some new active admins added other than myself
I've been playing almost only EU lately because it's the only server with people when I have time to play (mornings/early afternoon US Eastern). I wouldn't mind doing admin duty while I play, but at that time of day at least it doesn't seem like it's needed. The worst griefing I've seen was a teamate shoving me with his shield at the start of the round, and he said sorry when I complained that it actually lowered my HP bar.
Maybe they really like you and you get griefed/trolled because they have a hard time expressing themselves..?
