In 2006, Ben Edelman, a Harvard researcher, alleged that there were cases where Comscore software had been installed on users' computers without their knowledge. Comscore admitted that it was in discussion with a spyware firm called DollarRevenue but said that no contract was ever signed, and that once it realized DollarRevenue was distributing Comscore's software, months later, it took steps to prevent the DollarRevenue-distributed software from sending data to Comscore. Stanford IT notes that the monitoring software has been bundled with file sharing program iMesh without users being aware of it, although Comscore's relationship with iMesh was short-lived and occurred several years ago.
