How is this being done?

Question

Is it generating hits via my machine?

Answer 1

The site is taking friend IDs from users, and whenever a user visits the site, it loads MySpace profiles using the friend IDs in an iFrame, and changes to a new one every few seconds.

Essentially, your machine is used to generate hits for others.

Answer 2

Look at the source code for the page and you'll see parts of the hit script used.
