There's a question that was asked 4 years ago - this one - Can I cancel a transaction that has not been successfully broadcast yet?
The thing is, the chosen answer doesn't work well - as the comments later show, and also takes a long time, whereas the answer I gave isn't getting any visibility given it's way down and has zero votes.
This might not be the right place to ask this question, as perhaps it's more specific to the stackexchange platform than to the bitcoin stackexchange, but the question is - is it possible to flag an issue with the fact that the chosen answer might not be the best one?
