Well for starters you will need A Scammed/clean account and basic knowledge of the guild in question ( i was in this for a short time i knew GM's alts and way he acted) or you can take a shot in the dark with armory.
My first step was: Make a toon with a randomized name. Then i leveled it to 3 (to be safe) Went to orgrimmar and started.
I whispered an officer and said: Hey, its me (guildmaster) im deleting i need to deposit some stuff into a bank. Now i found out that he couldnt promote me SO. I whispered an officer and said: Hey, its me (guildmaster) im deleting this guy and need to put stuff in bank, But i cant see the other tabs. He then went on like WHERE WERE U WE WERE SUPPOSED TO GO (SOMEWHERE) TO BOOST (SOMEONE). Then when i said sorry was busy he said, how do i know you are (guild master)? I said: You dont have to promote me far enough to take only to deposit. He made me a member (99 access to all but 1 tab) I inspected it and said: There is still one tab i cannot deposit into. He promoted me one more time and said: did that work? i needed to promote you one more time. I was like yeah, thanks. (He was going on about private crap lol he knew gm in rl) SUCCESS I NOW HAD 1K STACKS FROM ALL TABS! NOW TO WORK! I quickly took all i could for one turn, ran to mailbox and sent to another toon on acc. I repeated until EVERYTHING was gone. i then put it all on ah and went and spammed/swore alot and racist in trade. Then i was banned for temp IN that time some of the auctions will sell and im sure all gms that recived ticket will see (oh hes banned must of been delt with) and bingo im free with a temp ban!!! i will answer simple questions now. Q:why wont the items be taken A: because already being banned, they will either assume its been dealt with or not take all stuff on ah. Q: why must i get a temp ban? A: cuz if you dont bliz wont think uve been dealt with. Q:why dont the idiot officers know the ranks they are promoting you to are able to withdraw A: because they are either real life friends that were auto officer or they dont pay attention. I hope this helped
