Seriously now, if there's a server which people like (in this case, MANY players. but even if there were only 10 users who likes the server), what's your problem with it ?
Sure there's something you don't like about the server. A server bug, lag, downtimes, my rules, my behavior, anything. You complaint once, okay, we understood that you don't like ProfessionalKO and you don't suggest it to the others. But continuing messing with us instead of ignoring us, then it's not just something which you don't like. It's called hate and jealousy.
There are hundred of people playing on the server. At least respect them.
