The worst thing I have ever done was in Animal Crossing (this was about 2 years ago). I went over to my sister's town and wrote on her bulletin board:
A couple days later, I went back and I wrote:
I was with her the time of this (to see her reaction), and she started laughing. I pretended to know nothing about the situation (which she bought), saying I'd never seen or heard anything like it in the game before. She wrote some smartass comment on the bulleting board how the TCM could go to hell or something along those lines. The next day, on the bulletin board...
She apologized on the bulletin board saying she didn't want her trees to be all chopped down (she was competing with my town for population and trying to get the golden axe). I created a new character file called "TCM" and sent her a letter from the Tree-Chopping Mafia saying that chopping had begun, and that she should never disrespect them ever again. Meanwhile, I bought about ten axes and went over to Ant Hill and began chopping down EVERY tree in her town. The next day she found the letter and tree stumps everywhere.
She still doesn't know I did it.

The Tree-Chopping Mafia is coming to town.

The Tree-Chopping Mafia is now in Ant Hill (her town name).
Please, do not do anything to upset us, and we will have no need
to chop down any of this town's trees.

The Tree-Chopping Mafia has been disrespected. We will begin to chop
trees immediately tomorrow morning.
