Collection of frequently used custom close reasons

Question

This question is partly inspired by this question. The difference is that this question doesn't care about "how" to create a good custom close reason. This question is to identify the good, already-in-use custom close reasons.

Part of the reason to collect these custom close reasons is captured in this question. That question beseeches our kindly SE overlords for additional off-topic custom close reasons. Regrettably, the more than reasonable response boiled down to "demonstrate which ones are being commonly used."

But we end up with a chicken-and-egg problem because using variants with similar phrasing makes it difficult to search for them and generate usage metrics.

And this question demonstrates that others in the community see a need for additional custom close reasons.

So this question has a two-fold purpose:

1. Identify and assemble the in-use custom close reasons
2. Provide a repository so others can re-use these close reasons and provide consistency in close reason messages.

Guessing Game
(hat tip to gnat and Robert Harvey)

This question appears to be off-topic because it is a "name that thing" question. "Name that thing" are bad questions for the same reasons that "identify this obscure TV show, film or book by its characters or story" are bad questions: you can't Google them, they aren't practical in any way, they don't help anyone else, and allowing them opens the door for the asking of other types of marginal questions.
