I also tried signing up for an account a while back when I got my Oculus Quest 2. I did use my real name, and they asked for all kinds of invasive personal information (including a scan of my driver's license and other forms of ID) and ultimately suspended my account too. So, to put a slightly different spin on your observation, they have pretty bad spam filters that happen to also be pretty good legitimate user filters.
