Please don’t take this the wrong way, but is this really necessary?
It comes off as a bit… hostile. Perhaps a touch counterproductive for a website who’s main goal is intelligent exchanges and welcoming atmosphere?
Unless it’s your government-appointed duty to keep the Art of Yo elite, you shouldn’t scare off folks with overt hostility. Lots of folks in this hobby are young and/or new to forum etiquette. Threatening to withhold your assistance if they can’t comply, for whatever reason, probably isn’t good either. I know it’s frustrating to see the same things asked repeatedly. :-[
Perhaps an FAQ could be put together? Make it sticky and noticeable, and folks will read it. If they still don’t get it, THEN you can foam at the mouth, attack, and make origami animals with their internal organs.
