They could by default for example require an identification of some sort, and then allow “non-ID” accounts to exist but require specific opt-in to view broadly or something along those lines.
More easily though you can just delete your account and then you don’t have to care about any of this crap.
But I’d be in favor of even an in-person verification system though the costs to do that would be unpalatable but I guess you could stand up a 3rd party to do that. Maybe there are better solutions out there that I’m not thinking of. I do know it’s very much against what the larger social media companies would want though because they actively want you to be outraged and misinformed since they make a lot of money off of that.
