    I just found an interesting server error log:

    Anybody know what is the meaning of this?

    That indicates a problem connecting to the gravatar service. You can't do anything about it other than to disable that feature if you don't want it:

    Admin CP -> Home -> Options -> User Registration -> Enable Gravatar Support

    So basicly, the spambot wanted to use gravatar but it cant, because the input email is not associated with gravatar?

    The issue was that the email input IS associated to a gravatar, but the gravatar service was down, or a connection could not be made (My guess is that gravatar.com was temporarily down)

    This would have happened with real users / spam bots if their email was associated to a gravatar at that particular time, and they tried to register

    I'm not sure of the out come (For most core XenForo, if a third party is down, an error doesn't propagate to the user, it just displays in your error logs)
