The NY Post was banned for violating the hacked materials policy, and they were unbanned after Twitter changed the policy. It wasn't 12 hours, but it was pretty quick. Meanwhile plenty of other media outlets published embarassing details about the laptop contents on Twitter, and were not banned... because they didn't violate the hacked materials policy. If underlying goal was to suppress the story about the laptop and prevent embarassment, why didn't they also ban those accounts?
Also, what exactly is the rule you want in place re: banning by social media platforms? Do you have a principle behind your positions that you can articulate?
