Today I had an idea to make a website where people could submit companies that do or don't drug test. It would be socially supported like ratemyprofessor.com. Do you think there would be a use for something like that?

I found a few sites online that have smallish lists, but they don't show companies that don't test (just as important in my opinion) and they don't encourage a social collaboration like I know r/trees would. I could see this being a valuable resource unless I'm missing a well-known site that does already something equivalent.

What do you think?

EDIT: Wow, such a great response! I guess I'll have to get started on it. :) I would appreciate any legal advice from informed sources. I don't see why this would be illegal, since the testing practices don't seem to be secret information to me. But obviously I have no training or expertise to go on.
