This does not seem worthy of a ban on the face of it. My sympathy goes out to OP.

The 18+ video chat is one of them... and (apparently) on the same domain is https://apps.apple.com/us/app/bitalert-bitcoin-ether-alert/i... (note the privacy policy and the terms and conditions and look at the top level service).

Having a service that is getting network traffic for both crypto related things and 18+ dating may have raised some algorithmic alarm bells.

And this is worthy of mentioning because?
