I have noticed a lot of complainers about the same people killing and stealing/griefing and the complainers(no offense) have even posted it on the forum. How about have don't trust list on the forum where if people know a player you can never trust they can post their name and the incident(s) and pics so people are warned ahead of time and don't lose their valuables.
*TR0LL
He has even the bane of VC or a long time don't teleport or let him teleport to you. He will kill, take, and grief you. Speaking to him is also a bad idea he is how his name implies....
* Eduartis
AKA BOUNTYHUNTER he like tr0ll will kill steal and grief. He will seem trustworthy at first but turn your back and you just got fucked. Anything gained wasn't through hard work.... It was other people's stuff.
