I found out from a user at Pixel Mansion the you can do the following to opt-out of the listing.
You need to add "_optout" to the end of your router's SSID Name. However, it should be noted that it can take up to several days for your network to be added to the opted-out list!!!
This is totally idiotic! You should not have to opt-out of anything to secure your devices! In my case, I have 3 consoles, 2 laptops, 1 PC and 2 tablets all connected to my WiFi. So now I'm supposed to go to every one of them and change the SSID again???
