I've seen some unsavory players in the very early mornings EST. There were two players that had a Knight chess piece symbol for a name and a Cross symbol for a name. Kept on saying "xaxaxaxa this games anti cheat is bad" and any time you tried to kill them they would kill you and teabag your corpse or keep on shooting at you as you were downed. On "Recent Players" they didn't show up either.
