Facebook has once again changed its rules for pages. A person has to be 'active' on your page a minimum of 3 times within any calendar month period. This means clicking 'like' on one of our pictures and/or posts or just leaving a short comment. If a person is not active on a page, as listed above, after a month of no activity, their 'like' will be removed from the page, as Facebook will have decided you are not interested in it.
