Uh fireattack? Some of these Black and White images [Monochrome] of the Touhou Tribute Arts Pool don't have Character tags on them.

I can't help but notice that since you don't tag them as so, maybe these weren't supposed to have them for a good reason - just only Copyright and Artist.

If that's the truth, then I have been messing up your posts.
For this and the future, should I stop putting Character tags on these Monochrome Touhou Project Tribute images?

No. I don't tag them just because i'm not familiar with Touhou Project. :D

Oh...then that means I'm okay so far.
