YTWWN is a blog where users have taken notice to a blatant rip off of a creative work. Recently, we found an interesting blog about the subject of (mostly) corporate rip-offs and copyright violations: You thought we wouldn't notice - some interesting reads, frequent updates and lots of discussions to follow. It is an open blog, so you can register and participate.
The above mentioned Art Newspaper has just recently moved to a new website. The old website, and some archives, are still on line, go to Old: The Art Newspaper and input Copyright in their search to find some 52 assorted articles about the subject (it goes back to 2012 only, so the article by Simon Stokes is no longer available).
A very good site to consult is this one:
