I just write the code, I'm not sure about their policy
A solution is encrypt url, no one will know your original link and can't report to file host
Give me examples
Use mcrypt to encrypt url with your own password, when people visit encrypt url, server will use your secret password to decrypt and get hot link, all members and reporters will only know direct link which is expired after few hours and cant use it to report your file
If you use mefiafire, you can check mylinkgen.com, each time you visit mylinkgen url, it will creat new clone link, your real link is alway safe
