People have a legal right to make comments about others as long as the comments are factual , if you can prove that the comments are not factual and they have done damage to your business , you have a legal right to take legal action .

There has been some legal cases recently where reviewers have made comments about hospitality businesses which have damaged the reputation of the business and legal action has resulted in the reviewers being made to pay large damage payments to the businesses .

General comments would be hard to assess without detailed information being  given ,'' worst experience '' is only a very general comment  as judged by the reviewer on their own judgement and their past experiences and is hard to prove untrue unless the reviewer gives further information which is not correct ,.
