The Cascade Bicycle Club in the Pacific Northwest threw me into one of these multi-minute Captchell vortexes when I tried to log in to my years-old account to renew my membership and register for one of their organized rides. I was already on the fence as to whether it would be worth paying to do these rides that I have already done several times over the years. That (ironically) dehumanizing experience pushed me over the edge. I didn't complete the Captchas, didn't log in, didn't renew my membership, and didn't register for anything this year.
