This is a pretty stupid question, but I was wondering if you could legally sue for online vandalism. The only example I can think of is griefing in a Minecraft server, since that is destruction of virtual property or very small amounts of unsaved physical disk space.
I'm not talking about hacking or DDos, but just going around and screwing up or blowing holes in other people's stuff in Minecraft (without hacking).
Get off the minecraft and get a life
It could be harassment or stalking, or cyberbullying if your state has a cyber bully law.
There's a legal group that looks for ways to sue people or criminally charge them for things like online griefing, or posting bad statements or pictures of someone.

You might want to look up the legal definition of vadalism.
No, since you would have suffered zero financial damages. Your recourse is to file a complaint with the makers of Minecraft.
