Didn't they just have their app removed from Google's Play Store for the presence child porn on their platform? I think the point might be that they cannot reasonably be expected police their platform to determine what porn is and is not acceptable. Surely there is going to be
a lot of porn posted that is crazy unacceptable, and I'm sure they don't want to have to sift through it all to discern what is what.
I am actually surprised porn is a big thing they are known for, considering their platform is aimed at kids/adolescents?
