Isn't trading duped items, like, bannable?

At the very least selling it for as much as genuine items without their knowledge is sharking.

More often than not 'Duped' when said lately means 'My account was hijacked and Valve restored all my hats, so there are two of X hat floating around'.

I always figured that stuff was made through packet injecting like in ragnarok and everquest.
