So from now on I will only be posting my art on my web site. I will link to my work on FB and Twitter, but will not be uploading to any social media site again. I just want to know where my art is and make sure that others will not profit off of my work.I get a warm fuzzy feeling when an artist realizes the importance of distributing one's artwork in making a living.

Recommended reading on Pinterest in the March issue of Arizona Attorney: Pinterest and User-Generated Content: Website Liability for Copyright Infringement.
Listed are six separate and exclusive rights of copyright owners, with the 4 below applying to image producers:
- copy or reproduce the work;
- distribute the work;
- display the work;
- make derivative works from the work
It's nice to be reminded about "distribute" and "display," and that there is no provision stating that "proper attribution" absolves infringers.
The article also points out that the DMCA requires that the ISP terminate the account of a "repeat infringer" in "appropriate circumstances" - something that Pinterest makes a big show of, with its fake strike system that never leads to account termination.
However a new "willfull blindness" standard may be applied to Pinterest from being eligible for the DMCA safe harbors.Let's hope the above comes to pass.
