[ SmokeDetector | MS ] Bad ns for domain in body, blacklisted website in body (196): Advantages of CompTIA Security+ Certification for Cyber Security Experts by sushanth p on math.SE

Not an answer (and the user who posted it knows it).

@JoséCarlosSantos Can be deleted now.

@MartinR Thank you.

Unrelated observation: There are more than 900 answers explicitly stating “This is not an answer”

@MartinR And almost double that when "This is" is removed

Also nice: “Not an answer, so please don't downvote.”

All 6 are by the same author and should really be comments with figures referred to as hyperlinks

Today I stumbled upon this useless answer which can be deleted in my opinion (a CAS dump without any explanation). OP did not improve the answer in the last four years, therefore it does not matter that he can not defend himself currently.

D1, D2, D3, D4

D5, D6, D7, D8

D9, D10, D11, D12

I just noticed that all answers to Show that all roots of a Polynomial must be real numbers have been deleted and the question locked, because it is from an active contest. That's fine with me, but what I am missing are the “comments below for references to the originating contest.”

@XanderHenderson: ^ Can you add a link or some information about the ongoing contest?

@MartinR It was credibly flagged as an exam question. There are no links, as it is not online.

I have a script which will remind me to reopen and undelete in a week.

I promise that I will get back to it next Friday (and, if I don't, please poke me).

@XanderHenderson Ok, I see. – Perhaps you can add some explaining comment to the question because the locked notice explicitly refers to it (just a suggestion).

@MartinR Done.

I had not noted that the lock notice made mention of comments below.

D1, D2, D3.

D4, D5, D6.

D7, D8, D9.

D10, D11, D12.

@MartinR Gone. I'm surprised you only today stumbled upon useless CAS output from this user...

Thanks, @AlexanderGruber, for helping out in the close review queue.

Also, thanks for your ongoing help in that queue, too!

@amWhy no problem

using close queue to kill time in my many "could've-been-an-email" meetings today

@AlexanderGruber hehehe! ;D

@ArcticChar I didn't have enough delete votes left today to vote on two of your posts, but I voted to delete all others that weren't already deleted. I'll check again tomorrow.

^^^@quid, @Xander. this user "Watermark Remover" has also made a poor suggested edit. math.stackexchange.com/review/suggested-edits/1475907

@amWhy I would say "I'll look into it," but it seems that it has been handled.

@XanderHenderson Indeed, I was one of the two who rejected it. But in light of the two comments/feeds from SmokeDetector about that user, it seemed that in a relatively short period of time that user was bent on causing trouble. But I just saw that user account is gone, so indeed, it's been handled. Thanks for the info!

@amWhy Indeed. I went to check it out, and the user was already gone. ;)
