As far as what you did to get banned, and what you do to piss admins off, a lot of it stems from perceptions of how you act on the forums. Your insistance on using lowercase letters is annoying, your constant passive aggressive whining angers mods, and your playing the victim when someone drops the ban hammer is just childish.
Personally my only beef with you is you telling me how to do my job.
I don't like that, but we have moved on from that, so no need to revisit it.
The thing is, when you first came back from your banning waaaaaay back in 08ish timeframe, you were fine. You were respectful, and did a lot to help the OCR TF2 community. Then something in your brain snapped and you became an insurmountable douche for what appeared like no reason (though I suspect that mini 4chan board you frequent had something to do with it).
Now to the task at hand. You were banned for griefing, and the offense was you placing and then immediatly destroying a sapper. Doing so caused another regular to complain, and as you turn off voice, you did not hear the warning that was given to you by Garian. We have been discussing this and most admins agree that turning off voice is not an excuse. Ignorance of the Law doesn't keep people from trouble. I have my problems with you, but I would personally lift your ban if you would apoligize to Garian.
Seriously, that's all you have to do.
I have said my peace on the matter.
