There is a sub for sanity checking mod actions, aita-style.
If you keep in mind it is for active unconfirmed situations, and that votes there are not meant to mark the cases of mod abuse, I think it can fill that niche.
I’ve had similar problems with kde apps on fdroid. I think they are rebuilding very often and that somehow gives a decent chance they are chaning the file you are downloading. So the store is correctly identifying the apk is not matching the info of the repo, because the repo is outdated compared to the file.
I suspect droidify had outdated repo info while fdroid did not. A refresh would have probably made it work on droidify too.
It kinda does. In android and windows you have some apps/windows appear fully black in all screenshots and recordings. For windows this is some drm functionality which programs can call up. It also allows locking audio devices etc.
