Infracting. Banning. Both of these are fine games, but wouldn't you like to feel good about it by giving others a sense of false accomplishment?
And that's where this game comes in.
At least partially based on the game Achievement Unlocked, the rules are simple: give the above player an achievement. The achievement must be named, and it must have a point value, and it must also have a good description of how they got it.
Value: X points
Description: Use BGMf.
(However, I would recommend that your achievements are somewhat harder than that.)
And that's all the rules I have for now. Have fun!
(NOTE: Of course, lock this if it's already been done.)
