I wouldn't call that scam.
It definitely would have been a scam if i took those accounts (he offered me to send credentials first) and not pay him afterwards.
But just accepting a deal and later rescinding does not fall under the Scam-category IMO.
Unethical? Yes.
Unfair? Yes.
Mean? Yes.
Where did you read I said you did a scam?
I just agreed to it was unethical.
Nothing else.
edit:
Is everybody high tonight?
