To be fair, you think it's cheap to host like 150 episodes(175 MB each) and expect the bandwidth to last a month? I'm surprised that Narutofan still has the old manga chapters to download..... AND that the links still works!
edit: This really isn't any different compared to services like streamload where they charge you per megabyte just to download at brazing speed.
edit 2: The pay thing is just an option for people who want to download and can't be bothered with sharing on bittorrent or for people who can't use bittorrent. It might be wrong if the guy wanted money, but who does it hurt? Is he charging a lot of money or something?
