Checking for MP3s

[GermyBoy]

Now I don't understand how these ISPs are actually checking to then report the downloader. Do they just check the extention? If so, why doesn't the WORLD just mass rename their mp3s to mp4 or something not likely to be checked?

Peace,

Be patient, little grasshopper. It will happen.

I have used a few of my own file extensions before. It would work.
