Have you tried using Tor yet, also potentially Mullvad Browser with a VPN since Mullvad’s Browser has similar anti-fingerprinting and anti-tracking capabilities but for use outside the Tor Network.
Also there is a lot of disinformation surrounding hardware based bans on Websites, typically pushed as fearmongering by Reddit’s moderators. Websites on modern secure browsers can’t read your hardware identifiers because modern secure web browsers are Sandboxed. Of course this doesn’t apply to Reddit’s mobile app so don’t use that ever really.
Also you need to use a different email since they check for matching emails.
I don’t see why the name should be different I mean Seinfeld is both the name of a show and the name of a person. I think it’s fine the way it is :)
