I believe that if there is a reason to blacklist tag proof, the same reasoning should also work for the plural - the tag proofs. Since this tag has been created recently, it is evidently not on the blacklist. Could the plural form be also blacklisted?

^{I assume that this probably should have been posted as a separate question. However, to me it seemed a bit redundant to create two posts about nearly identical issue.}

EDIT: The tag is now blacklisted. If a users tries to post a question with this tag, they get the following warning:

The 'proofs' tag is not allowed.

Use proof-writing if you'd like advice on the presentation of your proof, or proof-verification if you'd like feedback on its validity.

Otherwise, simply tag the question according to the area of mathematics it concerns.
