One thing that was brought up that I thought was valid was "vouching" for another member. There is a handful of guys on here that I know I will personally vouch for, but that level of trust doesn't just happen because they've been on the board for 7 months or a year and they haven't had any bad trades or botched GBs. That comes from meeting with them several times, talking on the phone, meeting their family, and being part of their circle of friends over an extended period of time.
Too often these days I see folks handing out their trust and personal assurances like a cheap flyer in front of a supermarket, to anyone and everyone. You never know what a man will do when under pressure or faced with terrible odds, and here at CP we've seen "good BOTLs" who have been hailed by the collective community as trustworthy, only to snap under pressure with whatever life was throwing at them and do unethical things and mock whatever trust was given to them. Hell, we had a guy here who maintained the "how not to be an asshat" guide suddenly turn into one and start stealing back from CP.
My point isn't to be taken as "Trust no one," or anything extreme like that, just be wise about who's corner you decide to sit in when shit starts flying because you may be held accountable for your endorsement. Some folks buy their way into circles of trust, and then some folks do things the right way. That's all I'm saying. I'm no authority by any means, just something I thought I'd throw in the ring.
