It would set a higher bar for a bot, but SMS wouldn’t stop them.

Is this really true?
Twilio is the biggest sms back end and it’s like $10 per number month or something.
$1.15/number/month, though that is still some cost.
You’re right, the cost would make it a huge filter for spam. But you could conceivably have 1000 accounts on a verified server for just over a grand.
