Hello, HQ here.
@anniebach if you could report that post again we will take a look at it. As far as we are aware we've dealt with any libellous posts but if one has slipped through the net please let us know and we will rectify.
As far as general moderation goes, we do try to delete any posts that we feel go too far whilst still allowing people to voice their opinions. We will continue to delete any posts we feel are racist or break any of our other guidelines so please do report anything you feel is amiss. We don't always get it right, we know, but please bear in mind moderation can sometimes be a very grey area and we're never going to please everyone. Thanks again for being our eyes in particularly busy times when it's not possible for us to see every post. HQ
