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.
You analogy is flawed. There is no evidence that bob123 is a rival account seller. Therefore, he had absolutely nothing to financial gain from eliminating competition. Second, regarding the other situation that you elude to, I have not supported or opposed that particular flag. However, I do believe that particular user's posts fall rather close to threats of violence against a particular ethnicity. It goes farther than mere "naughty words." However, it appears it falls just under what is considered an offense worthy of a ban.
Also, bob123's act is not equivalent to burning the particular product. All he did was reveal which products are for sale. It's rather dubious that we have market where it is detrimental to reveal that the product is for sale. Most legitimate businesses would welcome someone informing others exactly which products they have for sale. I'm sure that you don't mind if i post the links to these threads:

It is irrelevant if bob123 is a rival account seller or not. He still used deception to destroy the property of another. The point of the analogy is you can cause financial damage to others without direct financial (or any financial) incentive. It is in fact equivalent to burning his product because it is now valueless as a result. The fact that account sellers need to keep their products from being revealed is 100% the result of the fact there are dozens of people on this forum who feel it is their right to go around policing the forum by whatever arbitrary metrics they deem valid rather than the forum rules. It is circular logic. We need to destroy his product because we run around destroying his products.
