Reply and hide comments on Facebook pages
Given that in 99.9% of cases I’d always recommend leaving not so favourable comments in place, with your replies if required. A sanitised page achieves very little and will slowly decline – people have a right to their own opinions!
That said… once in a blue moon you might feel that you want to reply to someone but not have that visible to other fans… well you can.
If you reply to a comment (as the page) inline, and then hide the original comment it hides both.
