Have you considered phone number verification? Both minors and people in non-western countries are a lot more likely to have a phone than a credit card. Not sure how easy it is for fraudsters to get their hands on large quantities of phone numbers though.
I wonder, because Github actions are a thing, Github is likely to be facing the same issue, and is likely to have implemented mitigations already. Maybe you could piggyback on that effort and require Github auth?

- Yeahsureok 4y agoFree phone numbers to receive sms's are ubiquitous. Its trivial to bypass. Github actions wears the cost as a huge multinational and has anti-abuse mechanisms in place for CI runners but not account signups which again are simple to automate if it means free compute. None of these things are actual solutions, people abuse free tiers to run cryptominers and commit crime, they don't get dissuaded by that. A CC number is a much more serious threshold that solves nearly all of your problems in a day.
