The removal has already been reversed, and thus no further action is needed here:

In the future, care will be taken to ensure that payment types remain correct (via phone call to business or in-person surveys).  I will not touch crypto payment types personally unless it has been verified personally (in person by me), and will comment on relevant changesets according prior to removal.

I have previously encountered seemingly organized mappers updating the "check_date=*" in an automated fashion without verification that it still (or ever) exists.  I will comment and report those organized users going forwards without reverting or touching their tags.
