I can get thousands of valid phone numbers for temporary use in 15 minutes. I’d say they are both about equal.
No one needs quadrillions of anything, thousands is enough to do 99% of tasks.

You can look up carrier data on a phone number easily enough, and if you're in the industry you have a general idea of which carriers are the ones that actually follow the rules for registering a number. You filter on the ones that don't.
Not cheaply. Even on cheaper VoIP services, that would cost you $1,000+/month. Not a great price point if you're trying to spam something like a social network or post fake reviews, because each of your accounts is unlikely to generate enough to pay for the number.
Plus, many of the numbers will already be blacklisted because they're VoIP numbers or because they've been used for spam already.

My point is that there are ~8 billion possible phone numbers in the US, when you account for reserved numbers. Many are already in use, many are blacklisted. Each costs $6-12/year to own through the major VoIP services.
There are essentially infinite email addresses, and each costs ~$0/year.
Which one do you want to use as a point of friction for signing up for your service?
Nothing worked.
How?
