The real question is; if you create an account solely to extort people for money, would you (of 4 posts) make 3 scam related posts, and one conveniently placed post with your addy?
Not a chance; this is framing 101
BTW staff not moderating trust and scams is what gives scammers here what they need to create this kind of confusion. It's a bloody shame.
cheers
You can't blame it on staff policy. The policy is there because staff could get a decision wrong too (not to mention we don't have time to get involved with everybodies issues). Staff involvement could also prove inconclusive. Whoever tried the extortion whether it be ndnhc or someone else could have just used tor or another proxy. It would only be clear cut if they used a computer/connection or an account linked to someone else but they very likely didn't. Maybe you could ask BadBear if there's any links to him or someone else but like I said it'll still likely be inconclusive.
I feel the staff can help with the trust ratings and all in some way. It just has to be sorted out . And in some cases decisions can be taken without much consideration , for example https://bitcointalksearch.org/topic/ume-sent-a-message-for-begging-before-selling-me-this-account-1073373
The guy who actually did the message is still sitting without a negative rep, and whereas I still have it. And in case like this the guy TBZ doesn't even care to negative trust the person responsible. He just gave me the negative trust , even when all the proof has been posted.
