this_was_an_invalid_tag_name -> invalid_tag

can't suggest alias, but this seems like a troll entry to me.

I actually don't think this tag is even supposed to exist, the deleted posts with the tag don't actually have entries for the tag being added. It is really odd.

It seems more like an error code in that regard.

Edit: Especially since two of the deleted posts that have it are 18 and 21.

In that case it was at one time an implanted tag

The tag does serve a purpose, namely in that several blank space tags (the result of the system registering different whitespace characters as actual characters instead of spaces) are aliased to it. I agree that two different invalid tags aren’t necessary, and that the whitespace tags should be aliased over as well.

As funny as the tag and it's wiki description is, it's probably better to just alias it to invalid_tag.

You can still see the scar where e621 had the tag surgically removed... lol, I made a funny... yeah I know what you're probably thinking... post #2031535

I don think we should alias it away as doing so removes it's intent. IIRC it was a bug tracking feature so we could figure out who added the tag and when.
You can remove the tag from posts, but I am for keeping it just in case the null tag bug comes back.
