::"Former arbitrator, checkuser and oversighter" trumps admin, if someone wants to play that "mine's bigger than yours" game. I've given a warning on the article talk page for the moment, as hopefully this is just a good-faith misunderstanding as to what's considered appropriate content on Wikipedia. (The standards of Wikipedia were far lower back when  passed RFA, and if he's been away for a while he may genuinely think he's being helpful.) If the issue carries on, let me know and if need be I'll dish out a formal  warning. –
