I got hate mail from a Sheeva once who only spammed the air drop. I played him as Ermac, kept comboing him, then I swapped to Sektor for the second round, kept comboing him. His hate mail was 3 messages worth of him informing me of my lack of a life for knowing combos especially on TWO WHOLE CHARACTERS. Something about not having a girlfriend, not having a job, and in general being a failure.
I informed him that I understand he suffers from some sort of severe attention deficit disorder, and that if he could find it in heart to spend 5 minutes in training mode he'd learn the same combos I did (which are ones I learned on my own). I explained to him that Sheeva was a poor choice of character for beginner players if he was looking to be competitive in the online scene and gave him some hints and basic combos with Sheeva if he wanted to get better at her instead of swapping.
He proceeded to call me gay, repeated my lack of a life. I told him I was outside his window and when he went to bed I was going to do terrible things to him that would make gay seem like a poor choice of term. He shut up rather quickly.
Then the other day I sent him a "<3" randomly and got a "Fuck you.", was adorable.
