 ### Why so many accounts?
 
 In my opinion it's preferable to have multiple accounts on different homeservers for ensuring decentralisation instead of having a single authority in power and being able to issue commands from multiple servers in case of federation meltdown which multiple rooms experienced during the period of room version 9 before homeserver software started to nag on unintentionally open registration refusing to start. Additionally state resets are a good reason to keep old accounts around.
