Bunnycaramal scams using Double Accept. They host the giveaway at their den for a Spiked Collar and Rare Party Hat. When the scam starts, they announce it's double accept and decline.
They also said they cannot be rude, therefore they are not allowed call them out or get suspicious and the people at the scam are not allowed to watch, forcing them to trade if they don't want to get locked out. This lessens the witnesses and to make sure the people that want to trade are the only ones in the den. If the victim gets suspicious, calls the scammer out or if the scammer gets the trade they want, the victims get locked out of the den.
