Sometimes I search through my blacklisted terms to see if I've missed anything good despite it being blacklisted. While doing that I've noticed a lot of mistagged stuff so I decided to do an experiment. I searched two contradictory tags and found a lot of mistagged art. I've fixed most of it but there are probably other contradictions like this out there. A lot of this was tagged as anthro on anthro or anthro penetrating anthro despite there only being a human penetrating. I don't know why someone would make such an obvious error but it seems like it happens alot.

this has a lot. Anthro penetrating shouldn't be on most of these.
