My guess is that this is a direct response to all the claw stuff running on macs. I used to never get cf captchas from a mac + home IP (while getting plenty on my linux ws + work vpn). Now i've gotten 2 sites in the past week that not only show the captcha, but also loop once I click the human thing. Most likely mac + resIP is not a good signal anymore...
