I've started email the customer support of pages that have overzealous CF settings saying that it's a pain and that if they want to keep me as a customer they need to fix it.

Most give a canned response of "we can't do anything" ̄\_(ツ)_/ ̄ but some small sites do something. GitLab has the most annoying CF bouncer and I moved my company off them once I got the we can't do anything about it response.
