Hey, finally an answer after a year! :)

@Sathya: Ah, I just read your comment and didn't notice you'd edited the tags too. Thanks, hopefully this gets fixed soon. BTW do you guys let the SE devs know or does this need to be posted on meta.SE to draw their attention?

@Sathya: Naturally I can't access that link. Still, now that you've confirmed it isn't this a bug in your opinion? Doesn't it mean anyone can get rid of all close votes on their question simply by self deleting and then undeleting?

@Sathya: It's this one, although looks like the poster has again deleted it. If you look at the revision history you'll see how it was previously deleted and then undeleted within 10s, and this cleared my close vote. Shouldn't be too hard to test too. Just have any question voted to be closed (by non-mods of course) up to 4 times, then as the asker delete and undelete. If the votes disappear then that looks like a bug to me.

@random: Interesting, but not the same. In that case the original question (which the newer one was voted as a dupe of) was deleted, so the close-as-dupe votes on the latter were naturally removed by the system because they no longer made sense. In this case neither of the two questions have been deleted. Just that the newer one itself was deleted and undeleted, and that apparently made all close votes on it magically disappear. If you can confirm then this appears to be a bug that ought to be fixed.

Let's get it done then. :) What's the procedure BTW? Can any mod do it or do you have to get the SE devs involved?

I'm advocating these edits just to remove all ambiguity. Let's not have to explain that hardware rec is also covered and so on. After all it's a separate reason for closure so why not mention it on that page as well? More clarity won't hurt, that's for sure.
