It is all well and good that these lawless music traders be brought to justice for their abominable behavior. But the question remains of how exactly the RIAA is detecting piracy. Even Internet2 officials claim they are unaware how the RIAA traced the purportedly illegal activity on their own network. The RIAA itself won't disclose its methods, but it did say that its actions were lawful. And really, who are we to question?
However, there is speculation that the RIAA has recruited/bribed students at the colleges it targets to monitor file sharing networks, giving the RIAA the access tools it needs to find music traders. While this is yet unproven, it does seem like the sort of tactic the RIAA might employ. The question is now whether CMU students are more noble or broke.
I leave you with the screenshot at right, from a userlist on i2hub. The username "[CMU]RIAA" appeared on i2hub for less than 20 minutes on Monday and has not appeared since. Is this merely a student playing a joke, or perhaps something more sinister?
