Angie's List is a scam. After your company gets added they contact you and tell you that your company has been added and reviewed. If you'd like to have an enhanced listing you can pay us for that.
They specifically outlined to one of my vendors that what they would be paying for is good reviews. They achieve this for you in two ways. One is by paying people to write the reviews, the other is by using telemarketers who call current consumer members and pressure them to write good reviews for your company.
So the whole "we are acting in our members best interests" thing is bull! They have one interest in mind: their own.
Angie's List is not honest... you can never know if the reviews you're reading are true or not.
