Auction's

Have'nt you noticed how 'all of a sudden' there have been load's of costume's put up for auction?
although it's rare that there are costume's in the costume shop - according to roberti.
so how have people been able to get costume's?
so i investigated
i went onto youtube and typed in marapets and there are loads of cheat's in order to get item's!
what is your take on this?
