Hotlink protection prevents other sites from creating direct links to files on your website. Other sites may still link to unspecified file types below (for example, HTML files). An example of hotlinking would be to use an tag to display on another site an image hosted on our site. In the end, the other site consumes our bandwidth. This system tries to add all the sites it knows you have to the list.

The site is designed to protect the direct links of people who copy and paste in their sites without mentioning the original source and to protect the site and links from robots and all this to provide bandwidth only to the real people
