I agree as well.. People will always believe that it is fun to ruin peoples creations that they took hours or maybe days, weeks, or months to build. Some people can be like that and griefing will always exist because people think it is fun. I personally do not, I hate griefers..
I think why tripwire was added was mostly so you could stop griefers. Though it wouldnt be fun if there were no griefers. You would have less things to build because you wouldn't have to add traps for the griefers and that's pretty fun to me.
1. Ban them/Jail them/whatever your server does
2. Run BigBrother (Best mod ever)
3. Laugh about stupid griefers and go back to digging like a psychopath.
Maybe add in some lemons in there. Everything is better with lemons. Hell if people griefed with lemons I would be fine with it. I'd be a griefer.
BURN IT WITH THE LEMONS!
EDIT: Holy necro topics Batman!
