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.
That is not a legitimate comparison. A more realistic comparison would be you meet some one on Craig's List because you think they are selling a stolen bike, then you run it over with your car so they can sell it. Engaging in deception to damage the value of the accounts is not excusable just because some one suspects they might be stolen. You all need to get lives and stop pretending you are on an internet version of "COPS".
Or perhaps we should dispense with the stupid analogies and generalizations and take the facts at their face value. You think account farming is a legitimate "business" here. I don't. It's a scam.
You are the one who started with the stupid analogies. I don't have to agree it is a legitimate business in order to agree that the user still has property rights which were violated through deception. If the user is scamming then produce evidence of it and open a flag and I will support it. These are two separate issues and one does not justify the other.
