Is debatable_rating a valid tag?

No. Rating disputes should be brought up with a staff member or on the forums, not shoved into some random tag.

change category debatable_rating (0) -> invalid
create alias debatable_rating (0) -> invalid_tag (1)

Reason: See above.

You don't need to change the category for a tag being aliased away, and you can't rely on a single BUR to do it in the right order even if you did.

What is the rationale behind changing its category to invalid instead of aliasing to invalid tag? I don't see how it could be replaced with a valid tag. The only benefit I could see is that it draws staff attention to a post that has a debatable rating, but that is better done by reporting the post, contacting staff, or bringing it up in discord/forums.
