"I am the founder of a large college professor rating website, RateMyProfessors.com. Our users add about 300 new professors and about 1500 new ratings each day. It’s a free site, and we don’t even require students to sign up or login in order to make it easier to rate professors. One of the drawbacks of not requiring a login is that I’ve had many problems in the past with people adding fake professor names. […] I have implemented a professor verification system that automatically searches the web for the combination of both the teacher name and the school domain for all newly added professors, using the Google web API."
