<i>accounts with more than 10,000 followers should at least need two people to change key settings</i><p>For accounts that could start a war this might be necessary, but for celebrities with >10K followers this sounds expensive and unnecessary to me.<p>To me, it seems like you could instead ensure the admin view of every account has a timestamped log of recent settings changes, including changes done by admins, with a link to the profile of the admin responsible, and a button to suspend that admin account with one click.<p>This way, the security team could've seen that Elon Musk's account had just been reset by J. Random Employee minutes before tweeting the suspicious bitcoin tweet, messaged J. on Slack to be like "hey did you do that?", and suspended the compromised admin account within minutes.<p>Sure, some accounts might be briefly compromised initially, but it would be resolved in minutes and not the <i>hours</i> that it took Twitter, right? That seems fine for what <i>should</i> be a relatively low-likelihood, high-expense attack like compromised admin account (of course, you have to ensure that is the case).
