On the contrary, I think social media bans are poised to accomplish exactly what they're intended to: provide a convenient justification for forced identity verification across all websites.
The ones who will think twice are exactly the sort of people these laws are intended to punish: the dissenters, the wrong-thinkers, those who must be silenced. Either they choose not to verify and cease to use social media (successfully silenced), or they allow their wrong thoughts to be tied to their identity, such that they can be identified and punished accordingly.
The ones who will think twice will have to see their children ostracized because all the cools are on it except themselves.
I lean towards teen bans. We already have the same framework for cigarettes and alcohol. They didn't prevent teenage consumption 100% anyways but they did their job
I'd like to know that when I'm reading a comment, it's written (or at least endorsed) by a human being. Currently that's.. debatable, and it's only going to be more so. Entities with cash and resources can focus on the topics relevant to them and drown the conversation. I'd like to at least know that the idiotic replies I'm getting are real human idiots, and not astroturfing in one shape or another.
