Should posts where the present characters appear in multiple series from the same franchise and the artwork is clearly about one specific due to settings, commentary and characters, contain all the copyright tags regardless? With the Fate franchise especially, sometimes I want to find specific Koha-ace only, Fate/EXTRA CCC only or Fate/Stay Night only illusts, but I find other stuff, like I'm browsing the umbrella Fate (series).
Some examples: post #5062549, post #4975339, post #4979682, post #4466511, post #5045864 and post #4966337.
If you search for Heaven's Feel, you find Heaven's Feel/ambiguous art, that's great. If you search for pokemon_*, digimon_* or other franchises, same, you mostly get what you want.
I remove tags from time to time and could do some gardening, but I want to see others opinions to reach an understanding before doing anything major.
