What are some good Maplestory game scams

I know a few scams in maplestory. first you get 2 people or 2 computers you for example a 50 attack Korean fan, or any other rare item other people don't have so on one computer, you say selling Korean fan 50 attack for a rediculous price then on the other char standing far away in FM, say buying a 50 attack Korean fan for like 10 mil more than the one ur selling. someone buys your fan for like 2bil, then u log out. then u gained like 1.4bil. another one is the Ilbi scam where u fill up your use inventory but last space is like a blue pot then u put 22,222,222 mesos and accept for ilbis. even if he is fast enough, you wont have room so you don't get the ilbis then after like 4-9 times, he will go fast then you use the blue potion and you have 1 space. Now you put 2,222,222 mesos and accept for ilbis then he will accept fast so you get ilbis for 2.222222mil.
