There are out there certain organisations who are nort overly keen on p2p networks and they put up various fake files and worse in an attempt to bugger up the network. They often appear when you search for popular files and often appear as blocks of various files with 20 or 30 hosts offering the files.

There are a lot of posts on the subject

is an example coninued on page nine.

Hope this gives you an idea of what is going on. With a bit of experience you will get the feel of which files to avoid.
