Nope~ Actually, I know I'm capable of angering someone, there's still some people bearing grudges for reasons I can only guess, but I won't be angering someone or try to get on their bad side, so I'm not really afraid of any1, besides, as some have said, taking things personally on the net is hard to do and thus it's difficult to be afraid of what someone 'might' do. More than 90% of the time here on NB, the insults and provocations aren't even meant personally, they're mainly just misdirected.
Also, try not to rely too much on reputation and rumours, because most people described aren't that intimidating, it's you who make it scary by hiding behind all that.
