Scams:

Many scammers scam in different ways, some even work together! The first one is the decline all trades scam, don't trust anyone even if they start saying mean things like are you chicken because that's how they lower you into the trap. The next one is the rare or beta scam. That's when the scammer has a rare or beta, saying that if  they trade  a weak item they will give you the rare. Then, they run away. The same thing happens with membership scams. This scam is the famous scam when the scammer pretends to be famous and tricking people to send them rares. The last scam I know of is a scam that I don't quite understand. It's done with two scammers, lets say a scammer said I'll give you a rare spike for my list. The list may seem really rare but is not. The other scammer will have the spike and the victim will trade their rarest items to get it. Then, when they get the spike they will soon trade and realize they were tricked.
