Is Pollfish scam?

Any idea? Meanwhile the same apps are producing money from regular Startapp ads. Human support forwards me to their useless FAQ and closes the chat. User logs show "Quality" on the Disqualified Reason column most of the time, but others get "User Rejection" or "Profiling".

Conclusion: it's crap. Not a single cent produced. Kills webview processes due to some bug. Stay away.
