For anyone else who was kicked off GoodReads 9 hours ago, I finally have a response from their "support" team. Are you kidding me? It's a known bug, so thanks for letting us know? I've been completely unable to load the log-in page, never mind actually log in, and they don't even give an estimated turnaround time?
I've been hearing people around the place complaining about similar issues for the past week. I myself have two accounts, neither of which can access GR.
