This will be ignored just like cigarette warning labels were until enough people are effected negatively by the foul substances.
Exactly my first thought.
In this case the foul substance in social media is the many of the user accounts (people and bots) --truly a shit show.
It certainly has turned into that. Those on my ad lists on FB primarily stay within their groups because of this and never want anything abut themselves made public to the general FB environment.
Most of social media is a waste of time but is a symptom of the human condition.
They confuse social media as being social. I think, to be fully and truly social, one must engage more than just electronic communications.
