I've been blocking a bunch of IP addresses and every time I block one,
a new one (or five) pop up with about 100 requests / second. When I
check those IP addresses against http://whatismyipaddress.com/blacklist-check,
there's (almost) always a couple servers blocking it. So I think I am
being DOSd.

But:
(1) Is there anything I can do about this?
(2) How come these requests aren't showing up in the dashboard (under
Requests / Second)? I'm not seeing any spike there.
