sure i can explain it or this pic will prove it
*sorry that was indonesian server and im using indonesian language, but this is the translation:
date: 1-october-2013
badman2223 (old user): I want to sell this account, because I need some money
me: huh why? premium account? how much?
badman2223 (old user): 70K (in rupiahs), transfer through Mandiri Bank (Indonesian Bank)
me: have a number that works or active?
badman2223: sure, please sent your purchase confirmation here (sorry his cellphone number was censored due to save his privacy)
badman2223: this id has been sold to KingFrost for 70K IDR
this screen taken:
if this reply didn't prove anything, then i will take screenshot of my proof of transaction.
so,
first: I bought that ID from the old user in 1 October 2013
second: I didn't know anything about the old user behavior in any server
third: my bad, i should write that i was bought this account in my application
thanks before
