How would I go with blocking/banning on my feed a user that is making multiple users on lots of communities, there's this user cm0002 that keeps on popping up and noticing patterns especially in news stuff, and just content feels really off.

I am on voyager app on Android and been blocking them every time but they keep on making more and more and more accounts on other instances and always just incredibly suspicious.

Is there a way to block a username from any instance like block "cm0002@*" or something?

Been doing this for months ever sense I noticed this user/not and no matter what I do there's always a new instance they join and start posting in new communities that usually about local news in the US.
