Has reCaptcha been cracked?

By | August 28, 2009

I’m not sure what to say here, I have ReCaptcha on my blog to fight spam comments, and my idea was it was to stop bots from spamming the comments. Lately I have been getting 20-30 comment’s waiting for approval, ones like these:

– Yeah … Here people used to say: ABC teach – in all hut shout:).
– I really like your blog and i respect your work. I’ll be a frequent visitor.
– Horoshaya infa!.
– Very interesting and amusing subject. I read with great pleasure.
– Purely my IMHO – you can not make the choice. Good luck, think about it..

They seem to be coming mainly from .ru domains. Has anyone else using ReCaptcha noticed this recently?
