I've noticed that the user "Unevener" seems to have gone on a spree about 11 days ago of tagging a lot of posts which were previously tagged "sleep_sex" as "rape" and "forced"; see their tag history here: https://e621.net/post_versions?lr=428861&page=2&search%5Bupdater_id%5D=428861
I could understand if this was "questionable_consent" (it's non-consensual by default, and a little dubious if arranged beforehand), but this seems pretty overboard to me; a number of the posts they've tagged feature explicit consent (e.g. https://e621.net/posts/4340680, https://e621.net/posts/4274395), leading to the strange situation of a post being tagged both "consent" and "rape" at the same time.
I've reverted the two examples I posted above but I figured I should probably ask the community before doing any more.
