Right now I feel these people need to be scrutinized the most. They have been skating under the radar and posting just enough to do so:
Rikishi
The Undertaker
Stone Cold

These guys I can't get much of a read on. Sometimes I find what they say helpful and insightful, but mafia can do those things too. They've been active though so the more they post the better read I will get:
Bret Hart
The Rock

These two have been pretty much nonexistent. You can't really analyze their posts because they have too few posts. So they need to post more:
Buff Bagwell
Max Mini

For the record, I am pretty certain these guys aren't scum:
New Jack
Big Show
The Hardy BoyZ (though their failure to elaborate on stuff is undoing this)

And I don't know what the smurf to think about The Warrior. He's so into his character that it's hard to read his post for anything other than entertainment.

As for Ric Flair, well, he's obviously mafia.
