Yosup321 scams using the Giveaway Wheel Scam. They advertise they are giving away a Pink Spiked Collar at their den. When the victim arrives, they say if the victim claims or ask if this is a scam, they will not be entered to try to get the more gullible people to gift. They announce it's a wheel. However, they soon point out that you can give them items so you can get more spots on the wheel.
They also claim that the victim can only trade three items to 'make it fair for everyone'. This is most likely so people don't call them out for taking most of their items. After the items were given, they announce the winner. At the time, the winner was Laurenbestamy, but them being a spare is still under investigation. About a day after the scam, they were found wearing another Pink Spiked Collar.
