The tag check-my-proof has the following description in its tag wiki:
Questions which also contain a proof or a solution that needs to be checked for correctness and completeness.
There are currently 22 questions tagged in this way.
Unfortunately, this risks leading users to the (incorrect) impression that it's OK to ask a question where you present an exercise, show your solution, and ask whether the solution is correct and complete. (Apparently at least one user seems to have drawn this inference.)
Given the existence of this tag, it'd be completely understandable if users drew that inference -- but in fact, posting your solution to an exercise and asking others to grade it is out of scope for this site. It could be OK to ask a specific question about a specific aspect of your answer to an exercise (though even then it is often better to see if you can extract a more general conceptual question that's more likely to be helpful to others, if possible), but it's not OK to post your problem, post your solution, and ask others if your solution is correct and complete.
So, I suggest we eliminate the check-my-proof tag.
(If you agree with my proposal, I'd suggest a procedure along the following lines: I suggest we review all of the 22 questions currently tagged with that, evaluate them to see if they are in-scope for this site, close them if not, and in either case, remove the check-my-proof tag. While we're at it, let's look for other opportunities to improve those questions. Then, once we've eliminated all questions tagged that way, we can blacklist the tag.)
But before we start that, I want to ask for your opinions. Do you agree with me that the check-my-proof tag could give a misleading impression? Do you agree we should do something about it? Do you share my sense that it would be useful to eliminate the tag, or would you suggest some other remedy?
