When I mean by /disguise it just removes your rank tag and make your name yellow. Nothing else.@Ping Ether Gave a good method to stop this (he posted this on my factions suggestion)
But either way i think that if you want to fly in lobbies you have to have your rank on or it won't work OR ^^ Cause no hack makes particles appear when you fly
that will lead to Impersonating other players/staff /disguise should only affect skins not IGNS because you can hack with /disguise on and get someone else in trouble
