I did not see any others that I recognized but in a nutshell this 'Chad Lieberman' claimed to be the artist of hundreds of works (including some ripped works from famous artists) and was selling them for big money to line his pockets for years. Apparently he has rubbed shoulders with many in the media industry and if this 'Chad's' claim in one news article is true he is the nephew of senator Joseph Lieberman. Many artists have united to track him down and gather proof (thus the screenshots) to do a Class Action Lawsuit. Some works and artists have been notified but many have not yet been identified. 'Chad' (if that is his real name) has jumped/run from his website Art4Love ----> Markyourspot.com ------> MichaelPerezgallery.com in effort to keep his theft going.
There is a web archive site that would probably still have some of those deleted pages up. I can't remember the name or url for the site, but someone else will.
ETA, Got it here: Wayback Machine URL
The image looks familiar, but I don't know if it's from DPC. I found plenty of sites using it. More here.
You did pretty much the same as me (although the version you have is a mirror of the one I used), couldn't find a dpc link on the first 30 pages of the google search or the tineye search.
