Toribash is a OK community, but my problem is that many thinks Veb is some kinda god. And everyone praises him that way, even considering he is an main admin, with a small amount or no respect for the players. I know I am going to burn for this.
Runescape by far. It's filled with cocky 9 year olds that can't think of a comeback other than "Shut Up!1!!!" I decided to make a noob account because I was bored. I picked up an items that the other player kept dropping and he called me a noob. I showed him my account that was twice his level and he started swearing like hell so I said to stop the swearing because it doesn't make you look anymore mature and from then on, the only thing he would say was "shut up". What a welp!
Runescape's community and Tibia's community consists of roughly the same idiots, so nearly everything bukkit said about runescape can be applied to tibia.
So, I'd say tibia and runescape share the "glory" of having the worst community.
