Yeah... this is consistent with my experience. Try to keep calm and actually try again in a few hours.

It sounds like you have 2FA enabled so an account takeover is very unlikely. It sounds like you haven't violated the TOS in some egregious way, so actual ban is unlikely.

Most likely is there's some type of crazy cookie thing going on that is causing the auth system to vomit. It's shocking that this happens, but alas.
