Websites, social media and the Internet feed psuedonymity and anonymity while claiming "copyright" to their content. It is simple enough to give yourself a fake name. Even under a fake name you can own the copyright to content. Your Twitter name can be a meme, mantra or brand. Your eBay name can reflect the product you sell. No one needs to know your real identity. Even a website which has photos, videos and content can be fake, fake, fake. The more technical term is that the website owner could have "psuedonymity and/or anonymity".
