So there was this now closed MMO called Toontown I used to play. It was a very basic MMO and didn't have a lot of lore, since it was made for children in mind. Well anyway, the game was written in python and was very easy to latch on to and execute code into. On top of that, there were many inefficient client-to-server methods in the game, so you could basically heal yourself to 100% and the server wouldn't bat an eye. Anyhow an exploit was made that was basically a textbox that latched onto the process any you could execute code into the game. Now, one code people programmed was a clone code. This would make a clone of your character. This clone had no animations, it was in its T-pose, and did not move. It stayed where ever you were standing when you executed the code. Now these clones were actually refereed to by the server as players. So one day, a couple of exploiters decided to place clones all over the game. They would block doorways to different areas, and write out words with the clones. Every district (Districts were basically separate instances of the game) was full, and you couldn't log into the game because of the massive load. If you managed to log in, the game would instantly crash due to the amount of geometry the game had loaded for the clones. Now it took Disney (They ran the game) a while to fix the issue since they had to restart the servers and re-write the in-game code. I think they made it so that each "real" player must have an account, so the clones would be rejected by the server. Videos: This happened again in 2013, this time the clones would be congested in a single area in the sky. They appeared in all areas in the game, and all were doing random animations, like swimming or dancing. This time, it took 3 days for Disney to fix the issue.

On a non-clone note, one hacker by the name of "Magic Cat" was able to bypass the client entirely and execute code directly to the server. He was able to make bots that could teleport you anywhere in the game, move objects in the game around, and change his head to an animated image that was not in the game's files.
