Hey guys,
I just thought of a pretty good scam that only requires 3 things
1.Persons account name(no password required)-You can get there account name off of a pleveling site such as thsale.com or ur own source.
2.A 10 day guest pass or w/e
3.World Of Warcraft(duh)
Ok this is only for getting thier account banned and not taking thier chararcters/money but, what you do is sign up for a free account using the guest pass on thier account. make a lvl 1 char and go to a main city i.e. org, sw and make a spaming macro such as /y (w.e. u want) and spam it for about 30 min.
by then someone should report you, a new thing that blizzard does is report the main account of the trial account also. Now they can get in trouble w/ the trading site/buyer and get sued...maybe lol
Well there you go!
Edit

sorry for dbl) U can do this on a friends/someones house u hates comp w/o knowing their ac name by going into their logs in their WoW folder
