Yes, porn is unhealthy for the mind and affects more than most people really know and besides its just filmed prostitution, and I personally am not profound of prostitution, however some people even the pornstars could really enjoy it to be on the set and do what they do. Passion is a wide spectrum :) And about the NSFW posts you can disable or enable the auto-show function in your settings. But you probably knew this already. Have a nice day! :)
