I personally like distributing my posts between instances that I feel are trustworthy as it provides backup instances (thereby increasing the bus factor) which should cover the unfortunate situation of an instance shutting down.
Since we’re all federated I’m no longer forced to put all my eggs into 1 basket like reddit🤗
Displaying profile bios more prominently and encouraging the display of them would help everyone know if the user shared links to their other accounts or other SNS links and whatnot
This would also help fellow moderators and admins know if the newly created user is a real admin/mod that created a duplicate account or is just an impersonator
