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.
It's a "Big Tech" problem. Lots of people have experienced getting randomly banned from services with no obvious cause, and no way to get any resolution. I'm banned from AirBNB for example. No clue why and there was nothing that could have triggered it, because I hadn't used the service for like over six months when the ban happened, there were no disputes or other problems with hosts and my last host review had been glowing. They didn't even tell me it'd occurred, but they had been sending emails thanking me for being a part of the "community" just weeks before. Then I tried to log in, got a verification screen, entered the code and was told the account was terminated. Filed an appeal, got no useful response and that was the end of it.
If it was a free service I'd understand, but I've paid good money to AirBNB over the years. If you pay you expect to be treated like a customer, not an enemy, but SV tech firms have all copied the culture of Facebook/Twitter/Google. They seem to forget that when people give money they expect some sort of customer relationship as a consequence.
