This came up quite recently with the twitter account that posted historical pictures without attribution. Arguably they're showing people wonderful photographs that they would otherwise not see, however they were basically lifting archive photos and publishing them without giving any nod to the photographers or the institutes that provided them. http://petapixel.com/2014/01/24/make-money-twitter-ignore-copyright-creative-credit/ http://petapixel.com/2014/01/24/make-money-twitter-ignore-co... The attitude in most of these cases is innocent unless you can prove you own it and complain enough. Extreme example - is Google stealing from you because it aggregates your content, stores it, makes it easily searchable and then serves adverts to make money from it?
