There is a mod named Nightwing101, lately he been killing players in the pvp servers. I have suspicion that he is in vanish when he is killing a players. I do not have any evidences because is too hard to find any evidences when a player is in vanish. Please check on this mod.
Due to insufficient evidence this ban has been rejected and the player will not be banned. Please be sure to take screenshot(s), video(s) or have witnesses and fill out the form. - Kind Regards
