After doing reading on the meta I have come to realise that asking for a verification of a proof is not necessarily a good idea. Among other reasons, it has a fair chance to be left without an answer. I have come across some very helpful suggestions here and there.
I have, however, made mistakes in my youth, and asked questions about whether or not a reasoning is correct, and if there is a simpler one, such as the linked question. I think I am not the only one here to have erred in this way, and contributed to the 9,065 currently existing unanswered questions.
My question is, what should one do with a "check my proof" or "is there a simpler proof" type of question to close it? Two things that come to mind are:
Post a short CW answer saying that apparently no errors nor simplifications were found, and the question ought to be closed. Next, accept it as the answer.
Vote for closing the question on the grounds of not really being a question at all. (Possibly too strong, since I am under the impression that closing is reserved for really bad questions).
