The current wording:
This answer has severe formatting or content problems. This answer is unlikely to be salvageable through editing, and might need to be removed.
The wording of this flag leads me and I think a great many others to thing that content problems means that when the answer is very obviously wrong or more rant than answer it is the correct flag to use.
However across SE the mods disagree and decline this flag.
Could we reword this flag to be more specific like:
This answer is unintelligible or otherwise unreadable and is unlikely to be salvageable through editing, and might need to be removed.
