I am not sure if this is a repost but if it is just tell me.
STEP 1: Find a victim, i think you know where to go for that.
STEP 2: start talking to them like you really want to buy the account, act like a customer and not a scammer.
STEP 3: Once you make you deal with them and they say yes, Say that you want the Username and Password for the account before you send the paypal or whatever you are using. Say that once they get the money they can give you the rest of the info. Also tell them that just with the Username and Password you cant do much and they can easily recall their account.
STEP 4: this is when they will say yes or no. If they say no just move on, if they yes you are a sucess.. just get their username and password, then say something like " let me get on it really quick to see if it is legit " DO NOT CHANGE THE PASS. now ask for their paypal and pretend you are sending it.. While you are "Sending it" hop on their account.. sell everything and all their armor.. do what you want with it.. then transfer the gold to your account.
This has always worked for me and i hope it works for you also.
