Another fun fact, of course, is that CAPTCHAs not only suck for most people in general, they're especially frustrating for blind users, people who have privacy settings in their browser (hi Cloudflare!), etc.

It's one somewhat irritating tool in the toolbox, but honestly abuse-enabling services like disposable mail providers really just need to be taken down. We need to stop giving free help to criminals. Privacy is vitally important, but that should look more like a web of trust, not a fog of anonymity. No, every site shouldn't know your phone number, but they should be able to assume that your email provider does or knows enough about you to be confident you are a real person they can transact with.
