I have seen many sites where people can not add any comments. Mine is suppose to have that option (of people adding comments), but my hubby that is a computer guy made sure I will not have it activated. I did not want to add my daycare in facebook due to that reason. My husband suggested to do it to promote my daycare further... but if you have issues with a parent or as you mentioned a competitor wants to bring you down you are in trouble. Sorry that happen to you...
