Ive been getting SHITLOADS of emails lately from fake WoW admins trying to get my account detail, password, EVERYTHING. DONT DO IT, especially if you know your account hasn't been involved in any kind of that activity. If you really do get worried about it, call blizzard and they will tell you.
Certain things i found that made it fake:
-Shitty spelling and punctuation
-Fake websites like
www.worrldofwarrcraft.com (double r's)
-Claims against your account that arent true
-Different font of writing, The real blizzard uses like this ummm idk the font name but its like type writer, its really boxy
