A more proper analogy would be that some one who sells the precursor chemicals to manufacture cocaine getting their lab burned down by a vigilante after he gains access by pretending to be a customer. Selling accounts is not criminal, and even if it was burning down his property using a fraudulent agreement is still not acceptable.

There are plenty of words that have alternative common use meanings which do not hold to the technical and originally intended definition of the word. Fraud is a legal term and as such it has very structured metrics by which an act of fraud is determined. Let us look at the legal definition of fraud.

"Fraud

A false representation of a matter of fact—whether by words or by conduct, by false or misleading allegations, or by concealment of what should have been disclosed—that deceives and is intended to deceive another so that the individual will act upon it to her or his legal injury."

Clearly what bob123 did falls under this definition. Just because account sales fall under the more loose, casual, and colloquial use of the word is meaningless. One falls under the technical legal definition, one doesn't.

Regarding your argument that a contract was not formed, first of all the language in the flag says:

"SeW900 alleges: bob123 violated a casual or implied agreement, resulting in damages, in the specific act referenced here. bob123 did not make the victims of this act roughly whole, AND it is not the case that all of the victims forgave the act. It is not grossly inaccurate to say that the act occurred around June 2019. No previously-created flag covers this same act, unless the flag was created with inaccurate data preventing its acceptance."

So, even if your argument was correct that it was not technically a contract, an agreement was most certainly implied by any metric. However an actual technical contract was formed and documented here by bob123 himself.

Seller: "280$ ok,? !!"
Bob123: "Yes, 280 is good"
Seller: "ok" "do you pay me after PM" "?!"
Bob123: "Yes with escrow"

As you can see the three terms of a technical contract were in fact met.

Offer - The seller made an offer at a specific price point.

Acceptance of identical terms of the offer - Bob123 agreed to the price point on the stipulation his consideration of revealing the name/ownership of the account and they both agreed to identical terms.

Consideration - The seller provided consideration under this contract bringing it into effect.

I appreciate your genuine and civil discussion of the issues, but you are incorrect by your own metrics.

I do not agree the ends justify the means
