+1 I would say just let's get a few people, and clear it but the hassle of that mixed with the amount of anti-semi, and other slur type of stuff on there might as well just clear the whole thing. People before were able to keep up, and clear stuff off personally I know I have before but with the amount of stuff on there it's almost a whole game session to just remove the stuff by yourself.
The canvas has unfortunately been populated by lots of swastikas and slurs.
While this would normally be punished in any other form on GarnetGaming, the canvas is completely unmoderated - you can't figure out who placed what, or when.
"Just drawing over it" leads for it to be replaced near instantly, I actually think the Pink & Yellow one has a bot keeping it up.
It's a fun idea, but I feel unless there's a way to tell who's placing what on the canvas, it's just going to lead to more abuse.
