Well, to be fair to Krellin, I have banned people over the holidays, so I'd expect mods to be around to answer within 3 days too. I would recommend reaching out to Zultar. He's always very good with appeals, though he may take longer over the holidays.
"A Co-Owner can be contacted at
[email protected], if you want to appeal an admin or mod decision."
Now that said, Krellin whining about forum abuse is one of the funniest jokes I've seen in years, but he does at least deserve a response.
