Aliasing sai → invalid_tag
Link to alias

Reason:

or clean it up. or alias to something else. most of the time people use it to tag drawings that are drawn with paint tool sai and currently its just a huge mess that helps nobody.

Looks like one of those tags that users from other boorus might use. You know - users who don't know how to tag.

It is useless. But, before invalidating it, I would make sure there aren't any other pointless or typo'ed tags on its posts.

The weapons should probably be tagged as sai_(weapon) before that gets invalidated (or ambiguated?).

Denied. I've cleaned them up instead, moving most to sai_(weapon).

I also implied sai_(weapon) -> melee_weapon for later use.
