Google Voice blacklist is pretty common.

I have about a dozen credit cards, 4 bank accounts, mortgage, car payment, utility accounts, github 2fa, aws 2fa, Fidelity retirement, etc. Not one has an issue with my number. I did have some service refuse it, I want to say Twitter? But I'd definitely not consider it common. This is probably only the second or third time I've seen it, tbh.

  I'm going to guess the reason Anthropic do verified phone numbers is that, unlike email addresses, most people don't have an easy way to create multiple phone numbers. Since Anthropic accounts come with free rate-limited access to their models they're trying to avoid freeloaders who sign up for hundreds of accounts in order to work around those caps. Google Voice numbers are blocked because people can create multiple of those, which would allow them to circumvent those limits.

    What's the opportunity cost there? How much does a rate limited account cost and how much is a signup worth?

      These systems are likely under heavy sign up attacks and so must have a way to guard against that since their costs are quite high.

        I’m really curious where that line is and how it is identified. How much business is lost to the onboarding friction? Is it more or less than the cost of the attacks? On one extreme usage of the service is totally open to everyone. On the other it is completely locked down and nobody can use it ever. Clearly neither of those are workable. So it’s a question of how far to go with validation.

        There is just no choice at all. Due to cost of running those LLMs it would be very easy for adversary to spam bots to use their service for free.

  2fa and those services are different. LLM api calls are relatively costly and in demand so they must have a decent barrier of entry so people couldn't just spam automated accounts with automated requests to use the app for free. There are systems that abuse that and even existing API integrations are being abused by proxying and using for other purposes if they are free and don't have good security. Any place that wants to defend against bots can't trust those phone numbers.

For a sales lead? Why?
