Here is a page on Pinterest and copyright violations.

Now, if you happen to sell your original badge on e-bay and a Pinterest user pins it, you cannot complain about copyright.
Your picture does not have copyright because it is not artistic.
When FakeBadger puts up his creations, slidder and all, he does have copyright. It is on the badge, a creative object.
(You cannot publish a picture of the the Eiffeltower at night. The tower itself is out of copyright, but the guy who put up the bulbs has copyright)
Most of my Google searches have -pinterest because the site does not contribute anything positive to my query.
