What is sad is there are so many hacker forums out there. Honestly, I don't think both of your suggestions are that great of an idea. The signs of a hacker is an ok idea, but I'm not so sure about the hall of shame...
It's making fun of people. In Church, at least in my religion, we are told to hate the sin but to love the sinner. I think that making fun of hackers like you seem to be suggessting is not such a good idea because it sort of creates an us and them mentallity... almost in a bigoted, discriminatory type of way that could possibly some day get the good folks that run this site sued for libel and/or slander someday way down the line in the future. The admins tend to close threads that have the signs of hackerisms and ban the folks that posted those threads. That's the way to go. Would suck to have someone banned and forever put in to some sort of hall of shame who just didn't have a full grasp of the English Language, honestly wanted to learn fta, and just got banned for some reason because they posted some phrase incorrectly that hinted at Hacking even though what they posted was really intended to mean something else but the ban happened because some admin misinterpreted what they posted. I highly doubt that scenario would ever play out with current admins, but you never know what the future brings.
