Some of the Christian groups on facebook are under the constant attack of a sick terrorist who affiliates himself with Hezbollah.
He keeps pasting some nasty messages, flinging threats, and flooding the page. I tried to ban him, but the funny thing is that he does not seem to have joined the group or liked the page! I wonder how he can send messages and make comments without appearing among the people who like the page.

What could be his trick for that?
He is most likely a hacker who hates non-Muslims that organize facebook groups to criticize Islam.

His profile picture has some corpses lying on the floor with no head on them next to a lake of blood and a severed head facing the other two corpses. This guy may be a real murderer... He always sends this message: "I am going to cut your heads off". His nick is "I have come to be your death".

What can we do to stop this sick Islamic extremist? I reported abuse to facebook and requested that he be banned, but I know facebook may not take my report seriously. What is the secure way of getting him banned? Is it possible to write a formal letter explaining the problem and send it to facebook?
Peace,
