Just proposing another type of tag.
Generally_Accepted_Knowledge or, GAK for short.
Such a tag would have it's own color (much like Artist or Character tags), and only be searchable when searched as GAK:<tag>
The blacklist, however, could cover GAK tags without them having to be listed as such.
This would be useful for whena) Ambiguous_gender is used because of Tag What You See, but the character's gender is known because of external sources and/or other pages in a comic or pool. TWYS gets criticized a lot in this area, and having a GAK:male or GAK:female tag along with the normal Ambiguous_gender tag might stop all those stupid fights.b) A character's species is untaggable because people fight over what it looks like vs what everyone knows it is. An example might be Sea Salt. While I have yet to see anyone really cause a ruckus about this particular one, it COULD be claimed that SeaSalt can't be tagged as a dolmation because dalmations have spots all over their bodies not in rings in a few places, and therefore they do not see a dolmation, just a dog. Another example might be of a pic I've seen of a Ninetails (the pokemon) who's tails are tied together and the divisions not really drawn. The character is most definitely a ninetails, and is, in every way, drawn exactly like he always is, except that it looks as if he has one tail. Under TWYS, he can't have his species tagged. It would be useful to have GAK:Ninetails.
All in all I think GAK would only really work for gender, species, name, and perhaps gay, but could be useful nonetheless, without interfering with TWYS.
Just an idea :P Tired of seeing fights over it and not being able to find some pics because of technicalities. Totally understand if it's not possible/wanted.
Also this is NOT to undermine TWYS. I do understand the rule, and why we have it. I entirely agree that it eliminates many problems and makes finding what you're looking for much much easier. It is something we need in place; not removed and not screwed with.
However, it is not perfect, and some things fall through the cracks (like my examples above). They're not important enough things to warrant altering the TWYS rule, but an additional tag as I've described above which is searchable ONLY by adding the GAK: before the tag might placate the haters and help finding those oddballs without really compromising TWYS.
Thanks to everyone who pointed out a few key problems with this idea :)
By and large, what the discussions below have made me wonder the most though, is why the description box isn't used for all the outside info. Maybe all the left over fuss about this stuff could be cleared up by making one of those News boxes that points out the description feature and urges it's use?
The diversity of the search options got it's own News flash a while back, so people should be aware that they have the ability to search descriptions already, but that does almost nothing if the description boxes aren't used in the first place.
