That's the disturbing part, these people can only be themselves behind the screen.
I got active on FB 2016 - 15, but got turned off by the fakery, not just from strangers, but from people I knew in real life for whom I had to look the other way as they lied to others. And they're expecting you to support them, no less. Getting unfriended & blocked by IRL 'friends' for telling the truth was a blast.
