Do phone number requirements for account sign-ups effectively deter/mitigate spam?

  Truth social, last I checked, required a phone number and they’re almost exclusively made up of spam.

  Doubtful. Getting a temporary phone number is as easy as getting a temporary email address.

    Which is also why most services that use phone number for user verification ban VoIP numbers, making this basically useless

      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 strange browser extension installed).

      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. But that does add up after a while if you’re making tens of 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

      Really. Can you get a burner phone for anything close to $3/mo?

    There’s a service that gives you a dedicated Ukrainian number to receive texts at an email address for $15/year.

  I’ve never gotten a spam message on Signal.

    I’ve gotten a couple in the past few months, and it definitely seems to be a thing/have been a thing: howtogeek.com/…/why-youre-getting-so-much-signal-… androidpolice.com/signal-is-taking-the-fight-to-s…

  Google voice has been around for a long long time. But I can't use it for registration because it's classified as a voip
