And if you'd have said "****", would the mods have done anything...
I've heard stuff that would make a sailor blush. Mostly it's fine, but every now and then you come across a real moron. As far as I know though, the mods won't do anything unless, as said above, they get enough complaints, and it has to be somthing way worse than just a bit of potty mouth.
The only people i've complained about were one guy who were beat at team doubles who was pissed that we out-thought rather than out-skilled him, and sent me and my team mate voice messages of hate filled homophobic crap.
The other was similar, except this crazy chick in team doubles sent me a (racist) text message at the start of the game to delibrately try and destract me, then spent most of the game squatting on my corpse, followed by racally taunting us at the end of the game.
