I don't have the resources to test this out, but if I think this scam should work nearly all the time. Here is what you need.
1. A phishing site that looks like WorldofWarcraft.com's login screen.
2. EvilPage's fake message sender.Step 1: Find a guild website, and find the guild member's email addresses, the email address would be shown under their personal information
Step 2: Send them an Email with EvilPage. Make it say something like, "You have been reported for obscenities, you are on your last warning, to appeal this warning, go to [Phishing Site.]"
When they see the link to the login screen from a Blizzard Email, they most likely won't go to the original site to log in.
I haven't tested this out, but I believe that you should be able to scam accounts with a very high success rate. I would like it if somebody could respond, telling me if their scamming has been successful or unsuccessful.
