That's actually the wrong question to be asking here. The correct one is: What's right with this picture?
If anyone actually falls for this dreadful attempt at phishing they possibly deserve what's coming to them, but in case you're wondering:
- If a Blizzard employee whispers you in-game, it will be a GM with a character name. GM whispers usually pop up in a separate window to your chat frame, and their name is prefixed with <GM>. A level 1 "Blizzàrd" is highly suspect.
- Blizzard employees never, ever ask you for your account details, either in game or in other communications.
- Most GMs I've seen quoted or dealt with tend to have a very good grasp of the English language. This whisper uses the most dreadful grammar I've seen in a while!
- The site given is not even a Blizzard site. If in doubt, log into http://battle.net to check your account details.
