Subject: Re: Arbitrary DDoS PoC

Ah what a wonderful gem of pure and real research into todays upcoming
threats. Today is the day we learn to phear sites like xroxy.com
because God forbid some of those silly kids using their 9001 proxies
from their 56k dial-ups will over-run google, youtube, facebook, and
the world! Dear God what will we do?!?!? When will it end! Think of
the cute kittens you deprive us of evil proxy hackers!

Today is the day I learned hackers can cast magick upon outgoing
packets through proxies to somehow make them more bigger. I propose
these are some kind of Christian hackers with God on their side to
manipulate the very foundational laws of physics and electricity!

Excuse me Mr. Amorim but what God alas do you pray to for this? Is it
some kind of Christian Magick?
