Most of zlo players never beed at official bf4. They never saw a good players, so when they seen them at zlobf4 they do !voteban, report , crying and swallowing I've seen players at official bf4 that going to made you so mad that you're going to kill your parents just because you're big low noob that can't kill them but there is difference between zlo and official.
Lots of good players at official are with full gaming set. They know how to play, they know how to act good in every type of game. But if this noob never join at official bf4 they will never know how good player looks like.
I've been witness how noob admins banning pro players from official bf4 lots of times its kinda sad but also kinda funny, the person who is trying to revive the project with hosting server is killing it with banning people that playing good.
