Why does DarkRP get so much hate?

Its because of all the script kiddies out there. Server owners don't really like DarkRP since they know they will get some script kiddie who just fucks their entire server.
I suggest going with PropHunt since that gamemode does get a lot more players.

And until aStonedPenguin Shuts down his servers (Which will likely never happen)
we wont see a rise in popularity in other DarkRP
