What this scam will involve is to message a WoW Renting saying that you are willing to rent out your 'character' to them as long as they activate your account. Very simple.
1. Ok, first thing is to find a WoW renting service. Here's a couple that you could use, will add more later, shouldn't be too hard to find;
WoWPL - WoWpl.com
Rental Accounts - www.rentalaccounts.com/
2. After you've gotten onto they're MSN/AIM account, simply start a conversation with them, here's how mine went, very basic.

Make sure to ask for them to msg you after the account is activated/when they've started.
You'll probably get one of two responses most of the time
a) "OMG You got no 70s!!".
If you get this just ask extremely surprised and say that you probably got hacked.
OR you get
b) "Ok, your account is active and were gunna start, peace."
This is awsome. :P
Regardless of the two you get, simply change your password (or retrieve it if they changed it)
