1.) Start talking to the renter, say you want to rent your account, etc.
2.) Ask them a lot of questions, like do they use bots, what other things do they do, etc.
3.) After you have asked them all these, do not rent them your account. Instead say "i am reporting you to blizzard for doing things against the terms of service. I never planned on renting my account to you, this was simply an observational conversation of your company to obtain information to send in to blizzard."
4.) They are probably freaking the **** out.
5.) Tell them you can be "persuaded" to not send the information. Also be sure to discreetly or indiscreetly say that the company can be sued for a large amount of money for illegal activity that hurts blizzard.
6.) They will ask how, tell them you want gold, or a new account (don't ask for too much)
7.) They will most likely comply. HAHA SUCKERSSSS. You won't really send the information to blizzard by the way, just say you are going to.
8.) Make sure to use an alt/different account to collect your gold. After you have collected it, DELETE and remake the character you collected the gold on. This is extra security to make sure they don't try to get you banned.
9.) Congratulations! You have scammed the renters
