None of them care about you, none less either.. just make it up all the way, as long as the details are not already stored, they cant stop the account creation, unless they got humans doin their work.. (unlikely)
ok got you, I didn't explain myself properly.
Maybe I just need to rephrase the question: for what you know which is the one who asks less details during registration process?
I only ever use hotmail/outlook..
If you have an iphone, it's easier.. de-auth account, make new one rinse and repeat, who cares if you sold fone or not?
