Hold any rage replies until you have read exactly what I am proposing here, please.
I'm not taking in to account 'joke' tags. I'm also skipping over meta-information tags like absurd_res or original_character because they are useful and in fact I think there ought to be an actual tag category for that sort of non-visible but useful information. However, I digress so back on topic.
I think that these violations need to be either done away with so as to adhere closer to TWYS or be added as exceptions to the tag_what_you_see wiki page.
#1 Royalty
Many of the images under this tag do not have any visible means of determining that the character(s) present are infact Royalty. They do not possess typical symbols implying Royalty such as crowns, robes, thrones, long red carpets, numerous guards in decorative uniforms, displays of wealth, etc.
Examples: post #323861, post #322220, post #327170, post #326393
All "Princess" or "King" characters should not be aliased to "Princess" because that is not always visible from the image.
#2 Deity
With out referring to knowledge of the character's backgrounds outside of the images, how can these be determined to be god-like figures? What visually indicates a god or deific figure?
Examples: post #327362, post #300801, post #282109, post #316708
#3 Incest
Unless there is dialogue present in the picture there's no actual way to know if a picture is depicting incest or not. That being said, I do think this should be an acknowledged exception to TWYS due to it being a not uncommon kink.
Examples: post #318718, post #317629, post #306172, post #319131
#4 Parent, MILF, Sisters, Sibling, etc
As per Incest above, there's no real way of determining this from looking at the picture unless there are textual clues or otherwise similar things.
Examples: post #327218, post #320860, post #315193
#5 Humanized
How does one know this with out bringing in outside information about what the character is 'normally' like? I do think this tag serves a purpose and should be kept, but it's a pretty blatant violation of TWYS.
There are probably other exceptions which ought to be written down and listed in the tag_what_you_see wiki page or be done away with. This is not an argument against the existance of TWYS. I feel that the shortcomings of TWYS ought to be acknowledged and written out for the purpose of transparency. Once a list of candidate tags is produced, update the TWYS wiki page with the tags that can use additional external information such as incest or humanized.
