Try out Soulseek, as it's an increasingly popular P2P system.

It's so easy to do and takes up so little time and effort that it's almost a waste not to do it.

All you have to do is put the files in to a folder, designate that one as the one you want to share on the different networks, and leave yourself logged in to them in the background while you're doing other things.

I sometimes just leave myself connected to the P2Ps while sleeping. Wake up in the morning and find that the files have been uploaded dozens of times. Then when awake and wanting my own bandwidth/CPU usage for myself, shut them down. Restart em again at the end of the night before goin to sleep

Just make sure the folder you have set to share has nothing in it BUT the porn files you want to upload. Don't wanna leave your illegal music collection handy for all the world to see
