First of all i play in a private server called Kas-Wow there you cant change passwords so its cool.
All you need to do is create an ussles account and than make a lvl 1 char (you also need to have one high lvl like in kas wow it was max lvl 185 i had a rogue)
And you spam in LFG Want to trade Donor Rogue for <class you want> lvl 120+ (for example) And noobs will start w you like hell (got 7 accounts like that ) and when they ask you to proof you go on your other account and w him than come back into this account which you have the lvl 1 char.The noobs will say "so how does it work" you say "tll me your acc and pass first to make myself sure that you will trade if not i wont ! " and (you now noobs theyll do it instantly) when they give you their acc info you give them a fake one and go to their accounts Wholla you got noobs accounts
(sorry for my bad English) Noki Good Luck!
