This question already has an answer here:
What controls this? I've signed up for many g-mail accounts before without a phone number and for some reason I am being prompted for one. I tried clearing cookies. I am trying to sign up for a throwaway google account so I can download some chrome extensions. I do not want my computer\browser to be bound to me via a phone number for privacy concerns.
Please do not advice me to use a friend's phone number. This is not scaleable. I create many throwaways for different accounts. I am going to download my extensions and forget about it. It's also not fair for google to assume that everyone has a phone (I could be a bum using McDonalds wifi) or friends.
