"you have been kicked...next time banned"

What is the criteria for angry, salty speech around here? If someone is losing and purposely disconnects why can't you vent while waiting for the 2 minutes drained from your life by the creep to pass and jot down choice comments that might be sexually explicit at times? I always avoid any ethnic or national slurs and try to be humorous when possible (in a Monty Python sort of way), but frankly, what's the harm in an angry outburst in the face of horrible sportsmanship? Would you rather be cursed at a bit or be disconnected from your game?

Either you got the wrong guy or  haven´t a clue who you are or your rude and disgraceful comments. If I receive a message like that again I´ll report you . 

Not that I know of.

You have vocal cords for a reason.  That usually helps vent frustration if you're alone.  Plus, it can help you come up with any witty responses for the future.

Either that, or you can always disable the "enter" key on your computer, but I'm sure you would prefer the former option.

It's been emotional.

In a Monthy Pyton sort of way? Are you sure?

I've been playing so poorly lately that I'd be happy to spend 2 minutes to get a W in the books. 

Anyway, it is always, always inappropriate to insult an opponent. You wouldn't do it OTB, would you? Especially if the guy were 6'4" 250 pounds and meaner than crap. 

But what would you do if the OTB opponent just got up and never came back, forcing you to let his time run out before you could claim a win?

I'd sit there until I could claim the point. What else is there?

(See Steinitz versus von Bardeleben, Hastings 1895)

You obviously read the TOS when you joined, so you should already know the answer to your question.

Chess.com's overzealous profanity-catching program has driven me off of in-game chatting altogether. But now when people try to talk to me in OTB games i don't know what to do.

Bardeleben did it every time he lost? What a pigdog!
