The question Infimum of right derivative and infimum of left derivative are equal? was deleted by its author after receiving an answer. (Disclosure: It was me who wrote the answer, so I may be biased.) It looks like a sensible question to me and OP showed some attempt to solve it (even if it turned out to be wrong). – Do you think this is worth undeleting? Or has this been asked/answered before?

@MartinR Whether or not the question is of high quality, deleting after getting an answer is not really okay. Please feel free to flag such occurrences in the future.

@XanderHenderson Ok, I'll try to remember that!

@MartinR Recently, I flagged a question because the OP deleted after getting an answer (from me). A mod undeleted it and the OP deleted it once again. I flagged it again and it is undeleted now.

@JoséCarlosSantos Just in case you are wondering, the flag you raised on 14 August has not been forgotten.

@an4s From the style it even looks like a sockpuppet of this known cheater. @quid @XanderHenderson: Maybe a moderator can take a look.

@XanderHenderson Thank you. I really appretiate your concern.

@RRL DI even provides evidence that a user with 20k rep can be so incompetent and yet pretend to be competent.

Sorry... maybe not.

Let me look...

cv-pls functions I rather think that this is a duplicate, but I don't want to be too heavy handed about it. Which functions have the property f(ab)=f(a)+f(b)f(ab)=f(a)+f(b)?‭ - A-level Student‭ 2020-09-28 21:55:57Z
