Became fixated that I must be cheating and gave a steady stream of abuse round after round. You get used to some abuse on the internet but this I felt went beyond the pale and became quite malicious when I refused to be goaded. I quote:
53:07: *DEAD* Zelda00 : spastic u died again
53:53: *DEAD* Zelda00 : spastic u died again, tough to check that spot, right?
55:26: Zelda00 : give up u little spastic
56:04: Zelda00 : come spastic
56:28: Zelda00 : spastic dead
57:37: Zelda00 : spastic heard my reload and spammed
Whilst the insults were not particularly colourful or imaginative it was the underlying aggressiveness and antagonism which seemed wholly uncalled for. This demo will also give some people some ammunition on what camping spots to use to beat me

There is also a slightly sinister undertone with him suggesting he has a degree of control over the server lag which you will see empties the server towards the end. I think it's likely just to be hyperbole and grandiose claims but there was a degree of correlation in his deaths early on in a round and the lag starting, which he himself seems untroubled or phased by.
Anyway, thanks for your time and help, he's all yours! Felt I shouldn't let someone like this keep on abusing people on a whim.
