I think there is a bug with your software. I signed up using a test account and set my username as fren@ditto.pub
I logged in and in the notifications it says "you were granted the name fren@ditto.pub"
Then below I see "set name to fren@ditto.pub"
I click on that and nothing happens.
When I click on home I see a message "your username is under review"
It's a bug. I can't follow anyone because I don't have a username or that bug, I don't know
