Basicly you just explain your bans and how long and how you got them, I'll go first.
Just a day ago I got banned for "Participation in discussion of highly inappropriate sexual content", I got banned for 72 hours.
So, this is where I explain what happened It started with someone named Justinbieber entering trade channel and saying Hello. I casually greeted him and offered him some candy if he would enter my van. This involved into a little discussion of my current career as a kidnapper. I replied with "I wouldn't consider it kidnapping, more like misplacing children for a small cash price at their release". And then added "It might involve some sexual content aswell." , 1 hour later I got myself a 72 hour ban and a good laugh when I saw the ban.
It's a sad but awesome ban, but it still made me laugh for 3 minutes straight. :P
Now it's your turn to share your funny ban moments :P
