I'm afraid nothing will happen.
Most amateur webmasters don't know anything about such things and don't care.
That's a lot of content that Pinterest/Bing/Google can infringe upon without having to worry at all.
There will be a few, like me, that have gone from 10,000 image referrals per month to 100, who will make the decision to completely exclude image searches.
I'm blocking them in robots.txt and .htaccess.
