The only ones that can survive the robot apocalypse is large web services. Your reddits, and facebooks, and twitters, and SaaS-comment fields, and discords. They have the economies of scale to develop viable countermeasures, to hire teams of people to work on the problem full time and maybe at least keep up with the ever evolving bots.
The rest are forced to build web services with no interactivity, or seek shelter behind something like Cloudflare, which discriminates against specific browser configurations and uses IP reputation to selectively filter traffic.
