I can't think of many times I've gotten nasty messages actually. I know one guy who was crazy good at Aliens vs Predator sent me about 4 voice messages saying stuff like "MAN I KILLED YOU ALL 'YO I'MMA KICK YO' ASSSSSES" in a really obvious american accent, followed by ones in an Indian accent apologising and saying he didn't know who sent the messages.
It was pretty funny.
Apart from that I got some guy on SF2HD who used Boss Akuma (who is broken and actually banned from tournaments)(I'm 99% certain it was boss akuma anyway...) just saying stuff like "You fucking suck man, I owned you like my step-son" and various other nasty/offensive stuff.
I just replied with stuff like "LOL! Nice Akuma
" and "GGs pal!", being overly nice while filing complaints about him.
After one match he sent another angry message (he won all the matches I think, but i came close a few times) and I again sent him something really friendly. His response?
"Thanks, you're very good too."
