This may sound stupid, but seeing how yiff party was a pretty big site for what i assume is a long time, you would assume that the scraper involved with taking the content would have been copied and replicated by now. From what I'm seeing, this admin wasn't the best at running the site, which surprises me because that break my whole train of thought (bad admin->bad security->easy access to scraper->easy scraper copies), especially after the site went full furry with the amount of people that begged for their favorite creator to remain on the site.
