The work needed to maybe get it past outsourced customer support is not at all worth the effort for any site I don’t actually need to use

I’ve done this before, and the response is always “this is the first time I’ve seen this” and “you must be a bot operator”.

+1 to anybody who creates a site to name and shame CF customers who block legitimate traffic. For a few months now I've been taking screenshots every time this happens, but with no end goal. Complaining to the individual site owners feels like a lifetime commitment, and there are virtually none I need that badly.

How do you send them that when you can't access the contact form and/or contact information on their site because Cloudflare blocks it? (assuming a normal visitor, not someone who knows about whois etc.)

Send it to the domain contact from WHOIS information.

I have done that numerous times. Even sent a screen recording of the Cloudflare spinner of hell. The response is always the same: you must be running some shady software on your machine.

Cloudflare is acting as judge and executioner, and site owners never accept that the product may be faulty.

They will just tell you to use unmodified Chrome.

And soon with Web Integrity API they may start telling you to use Chrome on Windows or MacOS, rendering Linux completely unusable.
