Well, mine is kind of a long story. Back when wtbw made the MSN Nicker plugin I helped him test it for Trillian (the only IM client I was able to use in the university library due to user restrictions) and then wtbw told me about Plus! so I visited the forums, joined (account name was "The Philosopher" I think), but I never posted. I found #msgplus on EFnet (IRC) from whoising wtbw on there and hung around in there for a while with sock/wtbw then wtbw and I had an argument and I got banned from #msgplus EFnet because wtbw didn't want to talk to me. So I visisted the forums again and found out about the IRC server and found wtbw on there too. At this point I just wanted to make-up over this stupid argument, but he decided to ban me from the server instead of giving me a chance to talk to him.
So I trolled the forums with the account I had made and the account got banned/deleted. So I persistently visited the IRC server, using another nickname in an attempt to hide and stop being banned. I started to get to know people: Dane, segosa, kao... then I stayed on the server (and I'm still there today) and after a few months on IRC I made another forum account called "Exacerbate", which I subsequently had renamed to "Time" which is a nick I've been using on IRC for a few years. For clarification: I know wtbw in real life, we went to secondary school together, all in all I've known him a decade and I would consider him a close friend.
So blame wtbw for my spam/trolling. It's a great community on the most part and I'm glad to be a member. I guess I've been here over a year with this new account now and on IRC close to 2 years perhaps. Heh.
Edit: people are listing bans too? I think I've had two 24 hour bans and one longer ban? Not sure. Plus the deleted/banned account. =p
