Continued from topic #38673. Issue originally pointed out by MagnusEffect.

faceless and faceless_character confusingly have very different definitions, leading to heavy mistagging of faceless. Furthermore, there is a separate featureless_face tag, which seems to be used for what faceless's wiki says. I also found obscured_face, which is just a mess...

faceless_character - The character's face is off-screen or otherwise obscured from view. This is being tagged correctly.
faceless - Literally defined as having a "featureless face", so by definition it seems to be the same thing as the featureless_face tag, Understandably, it's commonly confused with faceless_character though. It's pretty split between the two interpretations.
featureless_face - Defined as characters with "a complete lack of eyes, nose, mouth." Despite the wiki, it is occasionally tagged when a character has only one of those three features if they are missing the other two... which makes sense.
obscured_face - No Wiki. Used for faceless_character, featureless_face, various shyguy- or mimikyu-esque "ghost faces" where the features are seemingly floating in a shadowy void or have a "drawn on" appearance, faces that are slightly obscured by an object, the character is simply not looking directly at the camera facing away from the camera... It's a mess.

So... uh, what do? Do we just have to invalidate faceless (945 posts) and obscured_face (459 posts)? Do any of the Wiki definitions need updating?

It might need tweaking but I just threw up a wiki for faceless_(disambiguation).
There's a handful of posts which should instead be disembodied_penis and/or disembodied_hand, but I'm assuming that's the usual for faceless_character?

I hadn't caught obscured_face yet, and to be honest I'm not sure where to send posts where only part of a character's face is hidden.

Of note, the faceless wiki is quite new, while the tag's history goes back 14 years. I'd call it as little as a redundancy that wasn't caught before now.
