So, most captchas don't seem to pose much of a barrier to bots that need to get round them.
A couple of months ago there was an article on the state of web scraping in 2016: https://goo.gl/eUtkRA. In it, the author easily identified and integrated one of many captcha solvers.
Worst case scenario, there is also crowdsourced mechanical turk style captcha solving as a service: e.g. https://anti-captcha.com.
I guess this raises the question as to whether captchas pose more of a barrier to users than bots, and whether they should be used at all?
