This sounds right. I can't imagine even trying to keep a forum like this on-topic when probably a good 75% of the posts are part of a tangent (including this one, when I think about it). I imagine most mods here have a "don't even bother" list that they keep or just sort of know in their heads, and that this one is on it.I think it just comes down to whether or not someone reports the post, i've been here a few years now and seen enough to think that's the case 90% of the time... and if you think about it, it makes sense, someone reports a post cause they find it annoying, mods come look and see it's off-topic, deletarooni, along with the posts quoting it, leaving folks wondering if the mods are stalking the thread, when in fact it was an ordinary user...
All that said, I would like to propose that "deletarooni" be established as the official LiL forum word for those occasions when a mod does step in and clean up.
