TBH I think pr0n and cam sites should lean in to Monero.

they need a phone number to sign up wnd are properaitary. shouldnt those be more focused on before talking about payments?

As much as I’d love to, ain’t going to happen. KYC payment and non-voip phone number lets them minimize the number of cheaters. That would probably be the official PR reason from them when it’s more about building a profile of your gaming taste and habits and selling that data to 3rd parties.
