@taboi:
It's clear you have no clue what you're talking about. You're a hypocrite. End of story. If you are going to threaten people with bans for violating copyright, then you should not be allowed to upload or download. Just like the police, you are expected to follow the rules that you are enforcing. Someone who is in clear violation of the rules has no business enforcing them. There's a saying about glass houses that fits here too.
And I know how copyright works, I am a photographer. There are very few limits to what can be copyrighted, NONE of which extend to porn (for example lists of raw data - such as names and telephone numbers - can not be copyrighted, however telephone books in published form can). The only people who claim porn can't be copyrighted are those who claim it is illegal on grounds of obscenity as they thump their bibles in your face. Governments disagree. ALL studio works are copyrighted, and NO member here has permission to upload them. Same goes for anything snatched off Xtube or Tumblr or the like if it was not created by that user, and same goes for screen grabs off Cam4 and Chaturbate. Period. If users actually followed the rules, this site would dry up instantly.
You are assuming that no one had the rights to distribute anything to the site. When in fact you need to assume otherwise unless it is proven to be false. People are innocent until proven guilty that is how most laws work in most countries.
If someone uploads something the site must maintain that they are the legal copyright holder or has the right to distribute the file. They cannot nor are they expected to research if that is true. It is up to the copyright holder to enforce their rights or loose them. Once it is proven/suggested that the uploader doesn't have these rights the site takes action and removes the ability to distribute the works.
