This is presented as a problem with "big tech", but I don't think most people would consider Tinder (Match Group) to be big tech? Instead, this kind of problem where you get flagged with no explanation or recourse seems to be common to consumer tech of all but the smallest scale. It's just very expensive to provide high quality individual support.
I think you don't recognize the scale of Match Group. They make two billion per year, they have 2000 staff, and they own basically every dating site.
