When I look at posts containing invalid_tag, I fully expect to add or correct other tags in addition to removing invalid_tag.
Of course, not everyone does this. I have no way of knowing if this is a widespread issue or not, but sometimes, after the occasional night of tagging, in the morning I'll refresh my page and see that there are no longer any posts with invalid_tag. However, when I refresh an image that contained invalid_tag the night before, I check its tag history and see that a user only removed the tag and did nothing else, even though there were signs that tags were missing.
To be clear, I only wish to discuss those who check posts with the sole intent of removing invalid_tag.
I believe this is a problem. Invalid_tag is much more useful to us if we use it to identify underlying problems with tagging. Simply removing it also removes the opportunity to critically look at these posts.
In an effort to change how invalid_tag is handled, I think updating the wiki would help.
What do you think? Should try anything else? If I'm not being clear on something, let me know - I'll try to explain my position on this a bit more.
