Basically from the Daily Mail:
$1:
Facebook has been forced to apologise after rejecting an ad that featured a photograph of plus-size model Tess Holliday.
Australian group Cherchez la Femme attempted to place an ad on the social media network last week to promote their latest body positive event, called Feminism and Fat, and were denied by Facebook.
The event, which is one of the group's monthly 'feminist talkshows' had a picture of Tess Holliday in a bikini as the main image for the event.
After a social media outcry and media coverage, Facebook has apologised and said the rejection of the ad was an 'error'.
"
The rejection of the ad was an error"

In fact that's worth a double-wink.
