Just one more on the Pinterest thing....
TOS link...
http://about.pinterest.com/copyright/
Highlights:
"Pinterest will take whatever action, in its sole discretion, it deems appropriate, including removal of the challenged material from the Site. DMCA Notice of Alleged Infringement ("Notice").
"I hereby state that I have a good faith belief that the disputed use of the copyrighted material or reference or link to such material is not authorized by the copyright owner, its agent, or the law (e.g., as a fair use)."
Now...if one uploaded an image on Pinterest and linked it back to ones personal or commercial website, I would think that this would NOT be considered "fair use".
I think if you uploaded it to
your a Pinterest account that you control and then displayed a hotlink to that image you your Pinterest account at your blog, Masterfile might very well have a case against you. Because in this case, your Pinterest account is, for all practical purposes "
your server" and you copied it to that server. So, in this case, you are for all practical purposes "hosting" the image. After all: you can delete it.
The fact that Pinterest doesn't charge you for the account is likely not relevant. So, in this case Perfect v. Amazon might not cover you. (I suspect it would not. But Masterfile still has to go to court and explain the distinction. But the way I see this, in this case you did make a copy-- to your Pinterest account. And you are displaying that copy-- both at Pinterest and at your blog. )
But if someone
else uploaded it to their Pinterest account which you have nothing to do with and you hotlinked the image they hosted, Perfect v. Amazon covers you. Masterfile can sue the person who uploaded the image to their Pinterest account and potentially win. But they won't prevail against all the people who hotlink.
As for Pinterest: All their TOS says is that
(a) If Masterfile sends them a take down notice, they will take down.
(b) If you repeatedly upload stuff that gets sent take down notices, they will ban you etc.
(c) If you upload copyrighted stuff, the same people who can send take down notices might sue you. That would be their choice. This simply a statement of fact. DMAC does protect Pinterest but not necessarily the individuals who upload.
But unless the masterfile chase here involves someone uploading stuff to Pinterest and then displaying that at their blog, the whole Pinterest thing is just a red herring.
