Have to find 10k+ profile pictures for a school course in generative art and social media. Need to quote a source, so I need a somewhat clean site/source. Preferably a site that willingly sells their users to the highest bidder. A found a site that sells what i want (profilenetwork .net), but they don't seem especially trustworthy, especially after finding a post about them on ripoffreport. Any experience with something like this?
