Our user base grew exponentially in the last couple of days, almost entirely from bot accounts. I broke the email verification step over the weekend, and the bots loved it. That is fixed, and I went on a bot account killing spree. Pew. Pew. Pew.
If you signed up for the site while registration was partly broken, your account may no longer exist. You would have gotten an error page when registering, and it would have been in the last few days. I apologize for the inconvenience. You’ll need to sign up again if your account died in the bot invasion.
