It's interesting that the word "scammed" is being used when bob123 wasn't enriched by even 1 satoshi for this. I don't see any evidence that bob123 used this acquired information to try and extort the OP. Also, punishing a whistle blower for revealing the truth with a red flag is a bit heavy handed, especially in this case.
I also don't think buying and selling accounts, in most cases, is legitimate. Someone is basically paying money so that they can present a reputation that does not truly represent them. Even if they are only purchasing it to get into a signature campaign, they are using it to land a gig that they probably don't legitimately qualify for.
If we are both
newspaper salesmen, and I burn down your newspaper stand, that doesn't directly provide me a profit does it? Yet I still violated the other salesman's property rights now didn't I? You all love using the widest interpretation possible to justify flags for people saying naughty words, but some one directly destroying the property of another doesn't count as risky behavior? The trust system is not your personal cudgel to be used against your opponents and kept from being used against those you agree with.
There is one big flaw here.
SeW900 is not a fucking newspaper salesman. He is not selling cars, he is not selling bitcoins, he is not selling GPU's. He is selling accounts.
And account sellers are not to be trusted.
