I would say this is only slightly better than the Chewbacca defense and not nearly as good as pleading insanity.
Also, while I have airbrushed out the name of the site you should know a few things:
1. This site is purely FOR PROFIT.
2. This site created different sections for the works of different copyright holders. Something tells me you can’t claim you don’t know what’s going on on your site when you have different sections for specific companies.
3. This site does not comply with DMCA notices.
4. This site is not “user uploaded content”. The only people able to post on this site are the site owners themselves. You can’t claim ignorance or the “we just index content” when you decide what content is indexed because you’re the one that uploaded it.
5. Despite being clear cut criminals, there will be a hoard of freeloaders commenting here to defend these actions.
