Most people have a misconception about being able to sue over their copyrighted work. Technically, yes a work is copyrighted the moment it's created. But in order to sue, you need to register your work.
@helleborine, I don't know what you create for a living (infographics I presume), but I have a hard time believing that you actually register every single piece you create with the Copyright Office since there are fees that can quickly add up. Not trying to say you're lying, but I am wondering do you register every single piece or just some?
Most people think they can sue over stolen website material and they actually cannot unless it is filed with the Copyright Office, and *only* if it was stolen *after* the date of registration.
Just some things to think about...
Regarding Pinterest though, I would suspect the majority of images found there are not actually registered and thus a case for a lawsuit can't be made. It's a loophole, yes, but a very modern and accepted one due to the nature of the internet and the existence of the DMCA. Statutory or not, most people simply don't have a case for damages.
