Well it's more like 5 million paying the ~15 a month, since half the player base is from China who pay per the hour and most of it goes to the company Blizzard works through to release the game there.
( not to mention rumors say the China servers may never come back up )
Riot police stormed a man's 30th birthday barbecue for 15 guests because it was advertised as an "all-night" party on Facebook.
Four police cars, a riot van, and a force helicopter were dispatched to a privately-owned field in a small village near Sowton, Devon in the UK on Saturday, ordering the party shut down or everyone would be arrested. The birthday barbecue was busted up before they even had a chance to plug the music in, reports the BBC ( http://news.bbc.co.uk/2/hi/uk_news/england/devon/8155441.stm )
It was about 4pm when eight officers with camouflage pants and body armor jumped out of their vehicles and ordered everyone out about an hour into the party. [...] The police had full-on camouflage trousers on and body-armour, it was ridiculous. There were also several plain-clothes officers as well [...] they kept on insisting it has been advertised it as an all-night rave on the internet. The times on it were put as "overnight" in case people wanted to sleep-over, but after being explained this they were still banging on saying it was advertised on the internet. They wouldn't accept it wasn't a rave. It was in a completely isolated field. http://www.dailymail.co.uk/news/article-1200310/Police-raid-30th-birthday-barbecue-man-used-Facebook-invite-friends.html"
