There is stupid laws where if you show age restricted content over a certain age you need to ask for people date of birth. There must be a game coming out or has been put on the store that has made Blizzard have to do it. It’s the same with steam they know my age and have to ask my age when I go to view certain games store pages. Weirdly enough I didn’t get asked on bnet yet.
The law is dumb, Like a 10 year old kid doesn’t know how to lie about a date of birth.
