I play 10NL and have found chatting to tilt to be just plain detrimental to my game. I'll poke at someone with insults, then use their 'tilt' as a read and be blown away when they show me the nuts. Or, I'll fake my own tilt, expecting calls when I have a hand, and the timing (or something) just ain't right; in this case, I have lost quality chances at slowplaying or otherwise utilizing better strategy.

So, I don't believe that tilting a player in chat "will come back to get me", but I have also stopped putting faith in the chatbox.

Maybe it is different at higher stakes. Or, maybe that is just my style...
