Aloha,
I have used Yahoo almost since it's inception, 1993 my original email was r********@yahoo.com, but since I was wan't 18 yet you asked for ID to verify age and security being what it is I thought it was a dumb request since I don't want to send my ID to anywhere on the internet.

Why was this done without any input?!!! I VEHEMENTLY WILL NEVER USE WHATSAPP SINCE THEY REQUIRE FULL ACCESS TO YOUR CONTACTS AND THAT IS THE NUMBER REASON FOR SECURITY BREACHES SINCE THE INCEPTION OF THE INTERNET! Does WhatsApp belong to Yahoo? That is the only logical reason I can think of to do this kind of unilateral decision making. Or the reverse WhatsApp bought Yahoo. Yahoo keep slipping over the years.
