Yes, it does. It makes it considerably harder to OCR the text.
They can do any number of things to make it more difficult to OCR besides making the text completely unreadable. If they are really worried about a script kiddie writing an OCR script with a server(s) powerful enough to run enough to cause a lot of problems, then they can put an image of a dog or a fish and tell us to type in what animal we see. It's ridiculous and unnecessary.
EDIT: Or use math questions, like Crono above said.
The only downfall of math questions is that you are greatly over-rating the intelligence and attention span of possible visitors to your site. There ARE stupid people out there and you take a risk in alienating them... not saying people can't figure out 4 + 3 or something, but bot-checks are annoying enough as is... sometimes if I get one wrong (due to a typo or just not paying enough attention) I just leave the site rather than messing with it . You're also really not attacking the source of the problem unless you use a visual or word-based math problem (four apples + three apples = ? apples... where apples is either spelled out or pictures of apples.) If a program can read text on a screen, certainly it can identify a basic arithmetic problem.
One of the key problems here, as the OP suggests, is that most sites are shifting to a user-submitted content. If you make it so users can't painlessly submit their content, they simply won't do it. Even if they do it once, if it's a hassle they won't spend time giving you more content.
Even AT is kind of a hassle in that is doesn't allow the usage of free email addresses. I like it, and being a tech forum they can get away with it, but I can only imagine that a few people every day go to register and stop in their tracks because they can't use their regular email address.
