Pretty interesting that you "don't even know why you were banned" but you know for sure you were on a "different server" when it happened. It WAS you, logged in on Famcraft,discussing the server name/ip with another person on Famcraft via /msg. We normally do not pardon advertisers. For any chance to return you will need to acknowledge what you did, and explain that you understand why it is against the rules, and assure it it will not happen again.

Dear RubensCherub
