This kind of thread invariably suggests to me there might be more to the story. I went to the homepage for the app. https://cuff.live/

I clicked on the Twitter link and Twitter shows the account suspended. https://twitter.com/cuffdating It's not that it makes the story here false. But getting banned by Twitter seems to take some deliberate efforts.

Also there's the similarly named "cuffing" It has been on the app store since 2015 and appears to have similar functions. https://apps.apple.com/us/app/cuffing-online-dating-app/id10...

Oh hell, I didn't even need to go to that much trouble. The OP had a similar post months ago and got advice from HN.
