These actors indeed need some training on social media & interactions! Chanel needs to intervene.
You being in public space: a ‘celebrity’: you have more responsibility and have to show more resolve! plus selective outrages : obvious groupism: disregard to genuine feedbacks: Paid PR ‘articles’ (In age of social media, very easy to spot) : and worse- putting all fans under one umbrella ‘toxic/ bot/ trolls/ abusers’ tag — all this won’t add up! 
This is a good reference to PS cast

honestly, this takes away a lot from show! 
If can’t reflect on your craft, can’t take criticism ( there will be good & bad both. Can’t help it) - don’t be in public life!
