Yes registration only CAPTCHA can be easily skipped by low paid humans, however it seems that the spams are created by machines — therefore adding a CAPTCHA when creating/editing pages for new users may help ;)

Given that every new spam user posts about 3 pages and then stop, I would say that bots hacked the CAPTCHA algorithm.

I think we should make registration harder and then we will be fine.

I suggest we use Google's nocaptch ReCaptcha, it's not only using hard problems to solve, but also browsing history & browser fingerprint and more to stop bots.
