How do I change my display name here?

I made this account really quickly many years ago while standing in a Verizon store just to activate my first iPhone. I thought I'd be able to come back and change my username at some point, but can't seem to figure out how to do so. I'm uncomfortable having my real name displayed and rarely use this forum because of that. I've searched and searched for ways to change that display name and someone said, in a post from 2020, that you have to make a request to the "Hosts." How does one go about contacting these mysterious and elusive entities?
