Are you fucking stupid? You literally just built a porn reverse image search tool. Think about it, all you need is a screen shot of a single frame of porn and you can find links to other vids with that person. This is a godsend for coomers.
Not to mention, the abuse potential of something like this is insane. Now anyone can just use a girls facebook profile or linkedin pic to find nudes - perfect for fapping or for blackmail. Copyright isn't gonna stop offiline copies from being taken, and the fact that most NCII out there exists of a subject that is unaware of said content being published, hence the people that need your tool the most proabably won't know it exists - until its too late.
It's so funny how you're trying to pass of this tool as "socially beneficial" when all it's gonna do is make the problem worse.<p>The internet and digital cameras being available to everyone was a mistake, when I come to power I'm just outright banning any transmission or storage of any photos of naked human bodies with the exception of medical reference pics. Or I'll just ban cellphones and home computers from civillian use entirely.<p>EDIT: I probably wouldn't ban the internet or home computers, but I'd at least completely ban porn, and use a tool like OPs to enforce such a ban with extreme prejudice. Anyone hosting or running a site with such content would face years of hard labor
