I don't take seniority into account at all. If someone rates a warning, I warn them whether it's their first day here or they're a Recognized Member.
As BOU said, nobody's ever been banned for flaming on a first offense. There's always a warning first, and they're added to the warned members list. I've never banned anyone who wasn't on the warned members list, that I can recall.
Of course, posting porn is different. We have a zero-tolerance policy towards pornography. First offense does equal a ban in that case.
