What's their solution for any other website? It seems like they'd have a very difficult time accessing ANY site.
In a quick search it seems like NoCaptcha is the accessible answer for the issues with regular Captchas. For the most part it seems to work, most of the complaints here seem to stem from people trying to actively block some of the evaluation metrics used by the checkbox (cookies,javascript,user strings,fingerprinting,etc) which makes them look very different from normal traffic which kind of by necessity makes them look a lot more like bots.
