It is usually done in order to abuse trust (thread started by a hero member looks more reputable then if it's started by a newbie) of forum users and bounty hunters. At least that's how it will look like, especially if it will be an altcoin payed campaign and there will be no escrow. It is a straight way to get tagged.
P.S. I have just looked through OP's post history and it doesn't look pretty good.
