A little thing I've started on 4 or 5 sites that has gotten over 4000+ posts. Ban people for whatever reason you can find!
The rules are this:
1. The person above you is banned for whatever reason you can come up with.
2. Being banned means nothing except that someone has banned you.
3. You may ban yourself as well.
4. You may not ban someone, but you will be banned
Examples: I ban myself for creating this thread. You're banned for reading this! I'm banned for having a beard. I'm banned for being online. That kind of thing. Have fun!
