They already did something similar for Experts Exchange a long time ago. They threatened to delist EE because of their deceptive SEO (including answers in search results, but requiring accounts when going to their page from Google). Google insisted the actual answers be listed. Deceptive search results made their service worse. Arguably Quora, Pinterest, et. al. are doing the same.
Maybe a flag for the pages that require accounts would be in order. But for the shills on Quora, well, why would Google show ads for businesses' services as top results for free - especially since that's the vast majority of their revenue?
