I doubt someone will just give you a party hat that you don't even know.
Maybe if you had vouches, or if you give something in return for the party hat, then give the party hat back for what you gave, then maybe you have a chance at getting one.
Brother if it was all this easy all the scamming noobs would be offering 8m for someone to trust them with a partyhat. Plus i doubt anyone who actually has a phat would want to risk or do anything dodgy for 8m rsgp lol.
Buy RSGP and buy a phat and re sell later or give collateral.
