I in now way encourage scamming... but this way of scamming someones account is used by scammers..
1. go to a website that serlls accounts or trades them like markee or buysellmmo
2. find a toon you like on there and message them on AIM
3. once you get all the talking done, start exchanging info.
4. you give him your UN first(GIve him a fake one) . then SQ/A.
<<<HERE IS WHERE YOUS SCAM THEM>>>
5. After he gives you his UN and SQ/A. exchange emails. and as soon as he confirms the email change do password recovery on the account. and blizz will send a new PW to YOUR email since he changed it.
6. from here you can transfer it to another account anc change names. or do w/e you want with it. It probably works best when there not the OO.
well thats the way ive seen scammers try to do it to me.
This is a way to scam AND a warning for what to watch out for =P
