Griefer = Garbage human being. These people are trash not only in Minecraft, but IRL too. There isn't a single one who is a good person in anyway, shape, or form. If I found one IRL, I would beat them to death. No bull.
I grief occasionally when i had the PC version, But only to people i didn't know. But i never blew up anyone's builds. My way of griefing was would be crouched and would occasionally toss a snowball at the victim. Then i'd let them wander around looking for a snow golem and while they did that i'd put blocks from other biomes around thier house...IE:Sandstone in Taiga, Netherrack in forest etc etc.
