Go by file size. If the file sizes are small, chances are it's a porn clip. Real movie files are much larger in size. Like Aaron stated, porn files are always renamed so filters won't help. Look at how many shares there are, if its that popular, chances are thats it's porn. You cant get rid of it. And neither can the P2P apps. There are always ways around filters.


edited: Full length movies are well over 700megs depending on file extensions. Tv shows etc are half that size. Think bigger in size when downloading from P2P.
