I can relate to this completely. One time our internet shut us off for a week or so and i came back and the board i always posted on, i was banned. I wasnt even around to do anything wrong. Turns out what happened was i stole my avatar from a webpage and the person changed the picture but kept the url the same and i was showing x rated stuff as my avatar. Learned my lesson not to take the avatar without permission and the admin at the site once i explained laughed and unbanned me. Hopefully its a much less emberassing version of that.
