Where's your Tinder bio in this article? I can't imagine creating a new account and publishing something obscene on any social platform today without being flagged or worse.
That one is the key. Likely some analytics service (Facebook?) has his phone associated with country A (his country of origin), and Tinder sees the registration coming in from country B (new country). That mismatch then triggered some anti-fraud signalling.
People who frequently travel/change residences or have bases in more than one place seem to get banned or blocked by all kinds of services.
Regardless of the intentions of the people designing these systems, I’d argue this is textbook systemic discrimination; you face issues only due to being different enough in the “wrong” way.
There's also calls out to crash-analytics, firebase, appsflyer and Google Analytics constantly. The app will function if all these services are blocked.
