Different sites/apps have different levels of security. Unfortunately, the Millennials don’t seem to value privacy. At least they are consistent in that they don’t value their own privacy or anyone else’s. Of course they have all the right opinions so if anyone finds out who is behind their avatar there will be no reason to cause them any harm.
It boggels my mind how those fools will put all of their info "out there", and even allow Amazon or Google to have a hot microphone running 24/7 in their homes.
