Very bad bullying in game. Reporting doesn't do anything.
Don't even bother playing this or wasting money here. You will just get harassed in cross-server. Gate-keeping C.S. monsters so you get nothing. Die hundreds of times for not even scraps of loot. If you get in a fight with one person in C.S. your whole guild gets nothing in C.S. and no amount of report will do anything to those players. Horrible game service. Horrible players.
There are better games out there to play and this is not one of them.
