Bots can buy phone numbers, hell, they can solve most captchas better than humans.
There’s a reason why Telegram is flooded with bots, Signal as of now has not been.
Telegram requires a phone number, so it clearly isn't working.
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.
Yeah, the dude has like 20 kids, just on pure chance one of them probably doesn't hate him (or at least pretends not to for the money).
At least Ballmer seemed like he enjoyed being stinking rich.

It's doing an absolutely terrible job of stopping spammers.
They could just stop requiring phone numbers, which would be a lot more privacy friendly.
Capitalists suddenly stop loving the free market when it hurts their profits

Wasn't this person like 14?
