Two times. One because me and my friend were doing a contest to see who could make the most emoticons (we were new back then) and the admin counted that as spam. The second time someone got my password and spammed Chuck Norris using my account
Lol, 3 times, once for talking to myself in the tmj mmo chat by myself, and savbot banned me for spam xD Once because I said "salt water" exactly like that.. but they thought i was being dirty or something, even though I was just talking about the ocean. And once because Tim Hortons>Starbucks xD
