as someone else said you are actually banned for a month, In truth you did violate their rules (and frankly ours too if the same happened here) trying to sell a watch outside of the for sale forum. The difference is that you would receive a warning here and have the opportunity to rectify the situation. It sounds like you caught a mod on a bad day and he decided to simply ban you. The funny part is he posted in the thread chastising you and letting you know you were being banned. Of course he was writing this to someone who can't read it since you were banned.
