@KReiser Are the tags added to the question here prior to your rollback not relevant?

(in particular, is the question not about affine-schemes?)

(this is a genuine question---I don't know algebraic geometry at all, but the phrase "affine scheme" is in the question, so it seems relevant...)

@XanderHenderson Why is this not open for deletion ? Is the score of $-3$ not only necessary for "new" posts ?

@Peter A question can be deleted either (a) 48 hours after it has been closed or (b) earlier, if it has a net score of -3 or lower.

The timing requirement is about the duration between closure and deletion, not the age of the question. So, theoretically, if question #1 on the site were to be closed today, you would still have to wait two days before voting to delete (unless it had a score of -3 or less).

@Peter why close this may i ask

@XanderHenderson So, it has been closed "recently", this is what I missed. Thank you.

@Peter Yes, I closed it just before mentioning it here.

@islamm Because it makes no sense to add the axiom that a theory is inconsistent and then even to claim that the theory keeps consistent if it was consistent before.

By the way, does anyone know the purpose of limiting the number of comments a user can mark per day (something like an upvote for a comment) ? And moreover, this limit is ridicoulously small.

@Peter Imagine a bot which pumps out a thousand comments every second.

(I mean, we can argue about where the limit should be, but I think we can all agree that some limit is required?)

This is definitely not an answer: math.stackexchange.com/a/4286133/42969. I had already successfully flagged it as NAA, but for some reason it hasn't been deleted yet.

@MartinR Would this user be the same people who used the suckpuppet?

@MartinR For your flag, my guess is that the "edit" kick it out of the the low quality queue (the review)
