Strafe was killed from chat for continuing an argument he was told to stop. Apparently he didn't like this, so he renamed himself to Strafes, got back into chat and after a while complained about his /kill. This earned him another /kill. Because I was afk for a few hours after that, I don't know exactly what happened afterwards, but now I found a user Shane that has 'multi' written all over it.
End result: Shane is banned and Strafes lost 40k (more than he had).
