I stopped visiting sites with image recognition reCAPTCHAs. It has to be one of the worst UX patterns ever devised. It's dirt cheap to automate them away so it doesn't really stop any self-respecting bot maker, and it comes at a price of being a huge pain in the ass for a real user. Every time I run into them I felt used and abused.

It's really sad. So much brain power and this is what they come up with.

Apologies for the rant, couldn't help it. ReCAPTCHA is one of very few things I genuinely hate.
