Regarding pre-log-in, that doesn't matter as IPs can be banned (and for a home, anything behind the router would all be banned).
So, I tried it from my phone off my network and had a few friends try, and they were all banned, too, even though they had never heard of the site before.
Then I was comfortable with it likely just being a glitch.
It did make me wonder and sad, though, as I can't imagine I had ever done anything here remotely bad enough to get banned, but I was already starting the grieving process of accepting my fate, just in case.
