Oh looky here, you've been talking about me and I didn't even feel my ears burn.
If I've killed you, you're either KOS to the CP, murdered an innocent in my presence, or you've killed another 5punker.
If it was near the Real Time Battle, I seem to remember your clan being openly hostile to 5punk so you probably died because of association.
We've got a list of people we kill, and if a name makes that list they are normally dead in under an hour. I suspect yours made that, even if it was later removed.
