The FAQ, in fact, says something very similar to what you claim it doesn't say:
> If the infringement appears on a personal blog, forum, or web page, I usually ignore it. If I have time, which I generally don’t, I may issue a takedown notice to remove infringing copies from personal sites most likely to feed downstream infringements. If the infringement occurs on a corporate or organizational webpage, product, broadcast, or similar, even if it is just a small internal image, I generally submit it to ImageRights.
> Social Media - Personal
People acting in a personal capacity are welcome to share my photographs on blogs, web pages, and social media accounts without prior permission, provided that all images are accompanied by a link back to www.alexanderwild.com. Failure to attribute an image properly may result in a takedown notice to the web host.
Attribution! A thousand times this. I wish twitter would enforce this policy or add a source field like tumblr on those various 1M+ reddit-scraping picture recycling accounts. @picpedant can't save the stories behind these images all by himself.
