This is a message at the head of one of the Facebook blogs we follow which speaks for itself. It's one of the reasons why we've never bothered with our own FB page. The denizins of cyberspace include a small number of negative and often nasty trolls who spoil things for not only the targets of their venom, but everyone.
We'd like to think there are none among our readers, but we know there are a handful. Nearly all social media blogs are labors of love, but when things stop being fun for the editors/curators/admins, then the likelihood is that the enjoyment that people could and should get from them will cease.
