Signs a "Blizzard" tell is probably a scam:
1.) No blue "BLIZZ" tag next to the teller's name.
2.) The website listed is not worldofwarcraft.com, wow-europe.com, wow-armory.com, blizzard.com, or battle.net; nor is it a subdomain of them.
3.) The teller seems to have forgotten how to speak grammatically.
You'd think scammers would gain access to better English before posting on the US servers...
