That's not the purpose. I just wanted it to be clearly visible for people to tell my home instance without having to check my account. (This is my alt account.)

I had to do it this way due to stupid username decision. I didn't yet know what Lemmy was, so I used the same username I used on SDF.org, which was yet another stupid decision: I just wanted to test it out without wasting my desired username, but a good user verified that account for me, thus I got stuck with the username.
