Can Moderators do this?

Why is it just because i just so happened to piss off a moderator, and later that day my old account seemed to be banned? All i did was continued on ahead during a mission while a Minion master was summoning , that person got angry because i didn't wait for her/him and she/he left. another person who also seemed to be angry left, then private messaged me later that what i did was wrong and i whispered him back and he said next pm will result in reports and when i came back to search forums for info it seemed my account was banned? Isn't he abusing his powers?

I can see from this thread that you apparently haven't even glanced at the rules. If you have a problem with moderation, you are not supposed to post it as a topic in the public forum. You need to PM me about this privately and I'll look into the situation. (that's rhetorical, since I know of the situation already, but you're not starting out well.)
