or someone can tell you ingame if you are there

This topic is completly worthless. Every Moderator must have proof that a griefer destroyed/edited, not just reports or names. A moderator must go in game and just /b the grief and undo the player. Simple as that. Banning players without confirmation from /about that they were assumed to be griefing is breaking the rules majorly.Besides its much easier just to go in game and /b the grief and undo them then it is to have names and assumptions and make sure they are all legit griefers.
