Proof of work. Example, bitcoin
How does this prove anything if using an emulator to bulk register bot accounts? Also, Signal Desktop is a thing.
It was the original purpose of the bitcoin algorithm to limit spam.
If you have to do a lot of maths that takes your computer (for example) 30 seconds, that means it costs 30 seconds of compute to create an account. Nothing to an average user, for a spammer that wants thousands of accounts it gets expensive.
Several captcha[0] libraries already use this and it's great for accessibility (normal captchas are terrible for it)
[0] I know, it's not technically a captcha.
Pow does not limit spam in bitcoin. Fees do. Pow is used as a decentralized election mecanism to distribute the block production.
