I know this has probably been said to death by now, but the UT AU community has a problem with wanting to revive problematic AUs and projects, dead projects that don't wanna be continued, and just general disrespect towards AU creators without even asking them permission to do things with their projects. All that effort could've been spent just making something more original and inspired by that one AU or project. It's why I generally don't do AU takes myself or I'm very selective about AU takes I participate/get interested in.

(not naming any specific project(s), but if you know, then you know)
