Having multiple accounts on different homeservers is preferable for many reasons such as ensuring decentralisation of power and being able to manage rooms from multiple places even with federation meltdown.
* matrix:u/mikaela.suomalainen:matrix.org - professional context where shouldersurfing may be a concern. Also {Element,SchildiChat}-{X,Android,iOS,Next}. (Predates my December 2021 namechange a bit)
* matrix:u/Ciblia:matrix.org - ~2016 retro MXID (nowadays they aren't allowed to have capital letters which I did by accident). Also less professional {Element,SchildiChat}-{X,Android,iOS,Next}.
* matrix:u/aminda:beeper.com - Beeper is building everything on top of Matrix while having their own clients and everything, so one would think it likely to be on all my devices and sending notifications, regardless of any primary status of the account. However it doesn't seem to like /e/OS and has fallen a bit out of use.
These accounts are deactivated and thus no longer usable by anyone. If they reappear, assume malicious homeserver and ACL on sight.
* matrix:u/aminda:the-apothecary.club - used to exist for accessibility testing animated avatars e.g. https://github.com/vector-im/element-web/issues/18442 and https://github.com/vector-im/hydrogen-web/issues/841 . I disagree with how they run their communities and thus have deactivated the account myself.
