My experience with captcha locked registration, is that at some point someone, most likely a human, provides an answer to at least one question. After this bots will register like crazy. On my site I had non googlable question, which holds bots for a month or two, but sooner or letter they will come.
The only way to deal with it, is to remove old questions and generate new ones.
