> bypassing Cloudflare CAPTCHAs

Can you say more about this? I've never encountered this problem in nearly a decade of running the same stack.

With the *arr stack, some of the trackers it uses to search for a torrent will present a captcha when Prowlerr queries it for a search. If you integrate FlareSolverr and set up Prowlerr to submit queries through it for the trackers that have CAPTCHAs, it won't get blocked by them.

Yep. It really isn’t nefarious or abusive. I keep mine slowed down to not scan often to be considerate. Even private trackers can require it now.
