These are some of my tips how to not get scammed.If there is thread like this then maybe better to delete this one.
TIP NUMBER ONE:
There is no such thing as WOW Game Master hack.
There are a lot of videos on Youtube that are saying download this program,
login with your account and you will have powers.
This will send your account user name and password to someone and he can
steal everything from your account.
TIP NUMBER TWO:
Tip number two is about free GameCards/WowLichKing KeyCode/Cataclysm Beta.
These all are scams.You will be redicted to site that looks like WOW and you will be asked to log in.This kind of scam are Phishing sites.They will send your information to him/her.
TIP NUMBER TREE:
Tip number tree is about addons.Download them from Curse.com if its .exe do not run it because it could be keylogger.And you will lose your details.
TIP NUMBER FOUR:
Never share your password with anyone.Because you know him/her doesn't mean he/she won't steal something from you.Its best to keep it for only yourself.
That's it i hope i helped you if you have any questions ask me.
And Remember:
Blizzard Employees will never ask you for your account name or password
