There was some spring cleaning of ads and stuff. The network of sites where Blizzplanet is hosted and is adopted as a sister site got a new ads company. For now it seems the rotation of ads contains the ever dreadful google ads that show “certain” untasteful ads I personally hate.
Not sure how long they will be in the rotation, but Umaro will take care of contacting the company to remove them. Don’t worry. The google ads won’t stay there. If they keep showing up in the next 24 hours, I will temporarily remove the skyscrapper code until I am sure they are gone.
These ads are controlled by the host in order to sustain hosting costs in a monthly basis. There may be other websites in the network, but I only know of Blizzplanet sharing servers with Diablo3.com and StarcraftTwo.com.
