Now, I'm certainly no virgin mary when it comes to cussing, but this guy is consistently foul-mouthed when he loses (not to mention stalling and booting).

There is a "Censor Swear Words" setting in the General Preferences too.
I agree it's unacceptable - that player has been given a warning (which will be final if it happens again). Thanks for letting me know.
