The Vultures strike again. What and how give the right? At same time the copyright holders are sitting still and waiting until a big amount of copyrighted photographs have been uploaded to Twitter, just to be able to say Twitter is making profit of it. If it's a private account posting that, then it's user's fault. The copyright holders should try to take that down. But what do they? Wait so they can sue. Vultures!!!!
