More people are seeing it make more sense to stand up to the RIAA rather than be abused by them, and as such filing complaints or counterclaims against them. In Michigan, several students have set themselves on a course to get the RIAA's detective lapdog, MediaSentry, exposed for the bad practices they use.
The latest complaint wasn't filed in courts, but rather with a state department, and is added onto a growing number of complaints against the company for using deceptive and legally questionable tactics for determining if someone is illegally sharing copyright works. Actions like this started to pick up just about a year ago when the RIAA was facing court for what they allowed MediaSentry to do, which spilled over into other complaints where students asked cases to be thrown out.
