Ah, maybe you've not read the whole thread, the mod in question has acknowledged his lack of knowledge (see what I did there) and as such edited his edit (did it again). Please take my comments tongue in cheek and don't get upset over words on an Internet forum.
Ah, I did see Scoosh's response and mea culpa. Mistakes should be allowed to happen and be forgiven if they're acknowledged and put right.
Having been a mod elsewhere, If I had to research to the n'th degree every last reference in every post I saw then I'd need a full time salaried position. Mods on here are volunteers of their own time, no?
As you point out, the mod in question held their hands up and put right their mistake, on what is after all only words on an internet forum (see what I did there - we can all play the patronising card), you still chose to let rip after that had happened, hardly fair play.
As for tongue in cheek, yeah, OK, maybe that's how it sounded in your head.
