I agree with you. Whenever I go on parkour (barely not at all) I get mad here and there. I might say some words that are "unpleasent". But, most of the games need individual mods that mainly advertise those servers. The only thing that I am worried about is that barley and mods play factions... (I spend most of my time in that game mode).
This is a fantastic idea! This would allow mods to focus on one server, as well as being more active on it. This would allow more hackers and rule breakers to be punished instead of annoying other players.
