So far I have seen only a few versions.
Screenshot of the original version is shown in Tim Campion's post: Revamping the closure reasons in 2022
The second one looked like this:
> MathOverflow is for mathematicians to ask each other questions about their research. See Math.StackExchange to ask general questions in mathematics
My post contains a screenshot where the second custom close reason was removed: Was the custom close reason mentioning Math.SE removed?
And then a new close reason was added - I've mentioned this in the main chatroom: chat.stackexchange.com/transcript/9369/2022/6/4
> This question is either a request to check work for correctness or an announcement of results.
This close reason should be used if a question either is announcing new results or asks to verify a proof or a preprint. It should also be used in situations where the work to be checked is included in the text of the post itself.

@AsafKaragila Any timeframe on when these difficulties might get solved? The missing close reason is one I (and I’m sure many other close voters) used the most often. — Emil Jeřábek yesterday
@EmilJeřábek: If not by tomorrow, then by Tuesday. Let me also add that it was a useless closing reason in 90% of the times it was used. Badly written questions shouldn't be sent elsewhere, they should just be closed. — Asaf Karagila ♦ yesterday
It's the ideal close reason for questions that are not quite suitable for migration, but nevertheless would be on-topic at math.SE, and last but not least, it serves the purpose of directing the OP to math.SE for their future questions. — Emil Jeřábek 20 hours ago
@EmilJeřábek The updated "not research level mathematics" close reason will point users to Math.SE, with a somewhat longer and better explanation. — Stefan Kohl ♦ 19 hours ago
@EmilJeřábek: It is the ideal, yes. But the bar is sufficiently high that hardly any question is ideal for that closing reason. — Asaf Karagila ♦ 17 mins ago
