“You too can boost your sim hack target profile with this off skew dying blue mark!”

On a more serious note, mobile phone numbers as KYC (due to global SIM laws requiring ID to purchase a SIM, pushed even into developing countries), AND security is a huge problem.

It stems from two key root problems. How do you limit membership or a trials to one (or very few) per person - often a credit card to sign up is an approach used too. And second problem is SIM as KYC - it means they don’t store your photo ID, but that’s already recorded via your SIM (that’s likely paid for your bank card, which had KYC as well).

The layers of tracking and control here is unacceptable for a free society’s people.

Nostr will have a similar challenge to limit things like free trials, signup credits, or memberships - however we can work towards KYC free approaches.

Ultimately decoupling individuals from a mobile phone number is critical for freedom. I proposed earlier that p2p and mesh net can help decentralise mobile data networks in the coming decade.
