Yelp automatically filters reviews to remove fake reviews and other content that violates its Content Guidelines. This helps to ensure that users see accurate and helpful information about businesses.

Yelp's automated filters are designed to identify reviews that are:

- Likely to be fake or fraudulent

- Written by users who have a conflict of interest with the business

- Potentially harmful or defamatory

- Inappropriate or offensive

In addition to its automated filters, Yelp also has a team of human moderators who review reviews and take action on those that violate its guidelines. This helps to ensure that Yelp users see only the most relevant and helpful information about businesses.

Here are some specific examples of the types of reviews that Yelp automatically filters:

- Reviews that are written by users who have a personal or professional relationship with the business owner or manager

- Reviews written by an owner, employee, or family member of the business

- Reviews written solely to promote or disparage a business using excessive or irrelevant information

- Reviews that contain profanity, hate speech, or other offensive language

- Reviews that contain personal information, such as phone numbers or email addresses

Yelp's automated filters are designed to be comprehensive and accurate, but they are not perfect. If you believe that a review has been filtered in error, you can appeal the decision by contacting Yelp's support team.
