I don’t know how well this works, but under Interface: Advanced Options, “Disable Spam Filter” is checked on by default. If you are still getting spam like I am, you may want to uncheck it. Why they would think you would want spam in the first place is very strange, but you may want to give this a shot.
Oh and one other thing, if you want the Blizzard splash page back, you can enable it on the login page. Just under the “Remember name” option.
Crap, I’d like to be on your servers then :(
I’ve had to use the new “report for spam” feature every single time I’ve logged on since the patch. I got 2 of them during the 30 minutes I was logged on at lunchtime
