Hi thanks for your answer.
And yes, of course i can always ask the owner to remove me. But to me this is a privacy and sovereignty thing.
What if the owner is not responsive, what if the owner is an annoying person i don't want to talk to anymore.
What if I am too lazy to write emails just to ask if someone would be so kind to remove me fron his server.
I should be in power to deny an invite and leave a server if I want to.
Server owners must not have the power to decide whether I am part of their project or not.
If you ask me it should be mandatory to leave the decision if a user is involved in a project by the user and not the server.
See Google has a similar problem which they don't fix.
Literally anyone can invite you to a google doc as an editor or viewer. And it leads to vast amounts of spam that lurks in your shared documents.
You can remove those docs, but as soon someone updates the doc, it will be displayed again.
Why? Because to this day it is not possible to actively deny an invite or leave a document that is shared with you.
I experience the accounts that I have in the internet as my personal spaces and I allow for entry or not. At least it should be like that.
