I think, like skywars or skyblock one of the two, that you can buy money on the server. The server now has a shop and some people can't get kills for money. If the server shop sold money then they can get kills by buying things from the op pvp shop. The ranks have a big advantage on this server with there OP kit. Players on this server think they have to hack to get money and get OP, but when they can buy money it might stop people from hacking. Now im not saying that all people will stop hacking because of it but some will.
