Ugh. Yes, but there are many fewer sites that actually need this than those that deploy it just so they can harvest emails. The only sites that need this are those where users are adding content and the site is moderated, and then login should only be required for moderated actions. So Yelp should require a login to leave a review, but not to read one.
