Some people do not recognize questions anymore. You write a lot of stuff that nobody's interested in, you could have just said: "no".
Edit, this was based on wrong information provided by @givesomefucks: ~~And that means that if I am following a person because they write useful things that I'm interested in or that I need for my work, I will loose connection when they suddenly move. That has nothing to do with what you call nonsense; it is a practical consequence of the Fediverse not having migration built in. Fediverse basically offers to create a new account, that is not migration.~~
Thanks a lot, very helpful
