It’s ALSO possible to generate virtual phone numbers for a small cost.
Using a cryptographic PoW is a different small cost.
Either way, it only takes a small cost to prevent mass bot registration.
You’re treating processing power and time as if it is 100% free just because it can be done in a VM. But it doesn’t matter if it is a VM. It is still going to require at least some certain threshold of processor time, and that processor time has a real cost. For the kind of place that can just spin up thousands of VMs and use it to do massive bot registration… they could just be mining bitcoins instead.
Nah bro, you are.
