Some is trying very hard to phish for my World of Warcraft account information what should I do?

Ok at first it was just one email, now Im getting like 2 or three of them a day. I have like 12 of them already.

The email addresses look pretty legit at first glance. But there is just one problem, I am not signed up to world of warcraft with this email so Blizzard has no way to know it. It has to be phishing.

This is so ridiculous its laughable. What can I do?
