Last.fm isn’t telling the RIAA that you’ve pirated the new U2 album. But you might be.

Why go to the hassle of trying to get data from websites when the users will hand it to you on a plate?

We’re sure that some of the people listening to the leaked album simply forgot that Last.fm tells other people what you’re listening to, but we’re also sure that a fair number of them were boasting. Look at me! I’ve got something I shouldn’t have! I am cool!
