Or indeed the users, who have to wade through trash invading their threads?
Or other legitimate users, who now have to answer captchas from CloudFlare just to access their favourite websites?
Ultimately this is a parasitical element, choking the internet. It will kill the things it profits from. Many will give up running these sites, you walk away with your $100k, and no one can ever do it again... you've not created anything of value, but destroyed it.
Parasites can solve captchas, people with accessibility issues and the poorest of people are the one being locked out.
Maybe my disability is CAPTCHA blindness.
The lesson here is that systems that rely on humans to do the 'moral' thing and fail otherwise are bad systems.
If $150k/year is “a bit richer” for you you could simply offer to pay that poster that much in exchange for stopping.
The other one that comes to mind is anacap, which I view as fringe. I read the comment threads sometimes and it leaves me with the impression that I'm the only one that thinks Von Mises and Rothbard are a bit out there.
