@TheSimpliFire It's also a duplicate. I had already voted to close as off topic, so I can't "dupe hammer" it closed. The dupe is posted in a comment to the question.
@XanderHenderson I saw that, and flagged it. Might very well be some bug with that queue.
This is a dupe of this. Same asker: target asked two days ago, dupe asked just now. (It can be closed as a dupe, even with no answer at target, because same asker asked both questions.)
Never mind, above comment from me: the asker self deleted the dupe. But the original (the linked question) is worthy of closure: one more close vote needed there.
@TheSimpliFire It's borderline. I agree it's not a very good question, but the asker seems genuinely confused by the actual mathematics underlying applying a polynomial to an operator. This is not at all trivial, hence I answered it because none of the existing answers even came close to properly addressing the issue.
@TheSimpliFire I agree with @user21820 that the question is fairly borderline. I am not going to vote to close it, but I also took action to remove it from the HNQ.
And, in the process, improved the question by giving it a more descriptive title (I hope).
@user21820 I think it's a PSQ worthy of closure. And the second question you posted just confirms my belief that the question is a PSQ seeking an answer only.
@amWhy Yes I'm not happy with both questions, and the second one is worse, which I did not see when I posted my answer. My main reason was only that the two existing answers failed to address the mathematical issue.
Some things happened yesterday that caused a need for us to (quickly) remove a site's eligibility to contribute to the list of hot network questions. For those of you not familiar with what we've come to call the 'HNQ' list, please visit the link; the list of questions shown as 'hot' on stackexch...
@RushabhMehta Flag the user's account, and mention that they posted a bunch of harassing comments below posts of yours, or where you commented, and provide links, e.g., to those you provide here: if it's a post of yours, include a link to it.
@Holo I don't think flagging a user harassing another user is further provocation. Or should we wait until it happens to you, where you get harassing comments, perhaps downvotes, and we all tell you to sit on it, and let it go, lest you further provoke them?
I by all means not think that the fact they deleted the comments makes everything okay but rather than pinging them here after they already ignored the first time I prefer to flag them and get over with this
@RushabhMehta Not a dumb question: flag one of their most recent posts. Mention this chat, with a link to it, and add details clarifying that you are flagging the post only to flag the user. I did that yesterday, and it worked.
@Holo Well, I'm not afraid of them. And I stand by my ping. If they're so naive to think that deleting a comment covers their tracks, they may as well know that doesn't erase their tracks. Hopefully, they'll stop doing so sooner rather than later.
@user597654 I'll wait for the moderators to deal with your harassment. Just don't be so naive to think you can harass a user, and then delete your comments. Site moderators, and SE staff see all comments, deleted or not.
@RushabhMehta Those questions ask about categories A and B... should I ask about the morphisms?
In any event, the more parsimonious explanation is that the question is from a homework exercise, and that two students from the same class are posing it.
It doesn't look much like a competition problem to me.
Someone is playing this site; three questions in 24 hours, each essentially the same, spells out one person gaming this site for homework completion, or one or more persons gaming this site for an active competition problem. Too much of a coincidence: TMoaC
I also meant to ping @Rushabh above in my last comment.
