You gotta be a real sicko to have the substack app installed and on top of that have their push notifications enabled

I think it could happen, but it would have to be a foss app and a paid service or funded by ads, because you need paid people to moderate services like that, moderation on lemmy is about civility and people being mean to eachother, but moderation on a dating app might involve dealing with sexual assault and other illegal things in a much more prominent way. Or it would have to be funded by a government or charity which is not very likely in the present.
