Review policy
- Reviews are published only after our team has checked (moderated) them. We do not publish personally identifiable information, defamation or statements that are not true.
- We never accept money to change rankings, ratings or whether something is listed.
- Reviews collected at the request of a school or organization are also published. In that case they are labeled as requested reviews; posts that hide such a request are not published.
