I've seen this (running a non-exit relay), though in my experience it's been a tiny fraction of sites rather than a majority. I don't get the CAPTCHA prompts for CloudFlare (unless I'm actually browsing via tor, not just my own IP address). Sites like https://atlas.torproject.org/ https://atlas.torproject.org/ will list (exit and non-exit) relays.
