Well i think almost every board or warez site has to bare some users what are submitting fake movies.

So how it will go along how you can fight that war against fakers.

First a DDL site should give a warning and not immediately ban some time
and give response what posts movies are the ones.

The Webmaster has to follow up first contact the uploader/poster and ask him to stop submitting fake movies or he will not be anymore posting submitted uploads this can go until perm ban from board .

If the uploader poster aggrees to stop , you wont submit his submissions to ddl , you will download some of his files to check , if its fake then push the mighty banbutton and you are free.
