Does ReCaptcha not work well for doing the ocr on something like this? Is it too expensive or something? All the ReCaptchas I see in the wild seem to be something other than natural language text.
Oops, sorry, your comment has made me realise that I accidentally linked @jerwin’s comment rather than the topic as a whole. Fixed now.
