Are you sure that your goal is to "shut all File Lockers" down?
I believe that there are some legitimate and legal uses for File Lockers, so you should be careful that you do not unknowingly alienate legitimate users of FL sites, and risk having them push back, and even possibly align with the illegal users of the FL sites.
Just as we legal adult site operators want the illegal operators out of our business, the legitimate users of FL's should be made into our allies, and could be strong supporters if we open their eyes about how some FL's are participating in/facilitating illegal activities, and hurting their company's reputation in the process (most legit companies do not want to be associated with CP and such).
We need to find File Lockers which are legit (if that business model is even sustainable with legit users), and direct the legit users to them. As they flee the shady FL companies, it will be even easier to target the bad guys, and it will remove whatever claim of legitimacy that they are trying to hide behind.
