@user21820 it's funny that you mentioned those answers because the other day I was looking for a proof of that limit and then I found that question. IIRC, I downvoted like ten of the answers given xd

And as I said before, I still can't vote to delete wrong (utterly wrong) answers.

@user170039 I was not clear enough; I meant "doubt that Robert Israel gave an answer to my interpretation of the question". I can accept if you doubt my interpretation, especially if you do not understand the answer. For what it's worth, the poster of the other answer that I said was wrong also agreed with me. In any case, if you do not understand the answer, you're free to ask in a comment to clarify it. It's written assuming the reader has abstract algebra background.

@Xam: Thanks! Yeap some of us can vote to delete, but we can't even do it unless the score is negative. That's the main issue with the current system; it serves the general SE purpose of collecting and sharing content, but fails to ensure (objective) mathematical correctness when experts can't delete.

Goodness @SmokeDetector

@SmokeDetector Flagged for moderator attention.

@SimplyBeautifulArt I'm actually wondering why so many got through; isn't there a spam filter?

@user21820 Yeah, I wonder the same

PSQ dupe.

@SimplyBeautifulArt Already did on the first; just voted to close on the second (no gold badge in the tags to hammer it closed!)

@amWhy :P

Closing as unclear?

math.stackexchange.com/questions/2442142/… May the question be closed.

Screaming title‌​.

May this question be deleted

@SimplyBeautifulArt two more delete votes

@SimplyBeautifulArt 2-1= 1 more delete vote :P

@amWhy Oh, right XD. I'm obviously good at math :P

@SimplyBeautifulArt lol

@SimplyBeautifulArt nothing posted from the user, currently. If they come back (if they haven't already), they'll probably register for a second (or third, or....) account.

Oh, that's a good example for something I wanna show you @amWhy

While they have no public content, you can see they have 1 badge:

stackoverflow.com/users/7770287/tsubaki?tab=badges

On stackoverflow that is

Since it is the editor badge, if you have enough rep on that site, you can actually view their deleted post

Ofc, usually not useful unless you plan on linking to that post.

@SimplyBeautifulArt Wow, I didn't know that. Cool!
