        To OP: it does add significant block to spammers so they may only create 5,000 accounts slowly instead of millions of accounts quickly.

        Most email services require a phone number or other email service to sign up if there is anything fishy about your connection/browser, and there can be hundreds of things, even just some specific browser extension installed, or you using the same mobile network IP as a spammer.

        And there are services where you can buy a real temporary 4G/5G number (non-VoIP) for a service for less than a dollar per use. Once a number has been used for that service it still has every other X number (thousands) of services it can be used for before it’s retired from the pool. But that does add up after a while if you’re making tens or hundreds of thousands of accounts.

    Requiring email of phone numbers isn’t always something virtuous like stopping spam. It’s also often about first party data acquisition. Even if some people use burner accounts, most won’t, and that means more data to share with advertisers.

    For Americans, yes… but everywhere else in the world phone numbers are cheap as dirt. When I was overseas in Spain my local number cost me 3 euros/month

          That exact price with a new phone? No.

          Like $10 a month or less by reusing phone hardware with new Sim cards to use occasionally for sms verifications? Yes.

          There was a service that only charged if the phone was used that day. A family member of mine would turn on their phone once a month, check messages, make a few calls, and then turn the phone off until the next month. I think they were paying about $2 a month.

              Not a clue. They got it from inside of one of the big box stores or grocery stores, so I guess from one of those little kiosks they sometimes have.
