Manual IP blocking?

This is not made possible with Shield as it’s not a viable security policy. You can read a little more about it here:

Thanks for the response, and I can appreciate the stance, but when the same IP from the same user has abused my site on frequent occasions, I’m happy to take the sledgehammer approach in aid of prevention. Especially as the only recourse I currently have is to ban the email associated, and that’s about as easy to circumvent as the offender signing up for another one.
