Once in a while I SO wish that I could specify a tag being not set, e.g. "-censored" or a certain artist. (E.g. depending on my mood I want to see a certain theme WITHOUT drawings of Julius Zimmerman. I think most of us (including me!) would say that he's a great artist, but when he is active in a certain area, he tends to dominate the pages. If I could sort him out, it would be much easier to see all other artists.)
Or similar purposes.

Would it be possible?
TIA
