because I suspect that the account was hacked, because the owner of the sashaabc account did not leave this message.
So you are saying someone hacked in to the account, made a single plagiarized post, and then logged out and never used the account again? You'll forgive me for being skeptical of your explanation.
The account owner has decided to make the bounty his main method of earnings and devotes 8-10 hours a day to this.
Then may I suggest that you/your friend find a real job?
