Cloudflare doesn't block bots. It's trivial to use residential proxies and your very obvious bot will only get blocked maybe 5% of the time when using rotating IPs.
- block larger cohorts of traffic, affect many real users
- babysit the rules to get them just right, lose time doing that
In my experience the residential proxies exist but are not that common and many aren't trying as hard as they could. It's really a war of which side wants to spend more attention on the problem.

- block larger cohorts of traffic, affect many real users
- babysit the rules to get them just right, lose time doing that
