If people would stop using FB, rather than complaining about it, perhaps this would not be an issue?
Perhaps the answer is to make the concept of social networks no longer cool; or even make them undesirable. I think it's pretty clear they are not, anyways.
I use whatsapp, line, email and photo sharing services that allow me to easily share and communicate thoughts and media with exactly who I want. It's more personal, not addictive, creates better relationships, and helps me focus more on who I am rather than how others perceive me. And of course I don't have to use facebook and be a part of all its oft-criticized problems.
For hundreds of millions of people Facebook is the messaging system. There's postal, telephone, email, FB messaging. It's also the most used. I think you need to come up with solutions that assume it, or an equivalent, will continue to be a principle and primary means of communication for billions of people.
Just the myriad of other articles complaining about FB implicitly promoting hate by taking no responsibility for what is posted.
