Facebook and phone numbers

Bacchisio

Hi everyone!
A friend of mine asked me to create him an extra Facebook account, because he can't do it (he's not keen on informatics). So I said “what's the problem”: a new email account and then some fictitious data and the work is done... but it wasn't so easy. I created one, but then at the second one appears a notice which asks me to confirm the account with an sms. Could it be maybe the IP number? New email, different IP, even deleting the cookies, changing browser that's what it comes out. I've tried to reboot the computer, but I'm pretty sure that the problem would remain even changing computer, it'd bypass it at at first, but I believe the problem would arise again.
At this point it's becoming a personal challenge, I'm trying to understand how can Facebook understand that it's always me creating a new account rather than someone who's activating his/her first account.
Do you have any ideas on Facebook adopting a standard that asks the phone number? How can someone then activate an account from an internet point? Do they have to put their phone number?
Thank you

FB are moving to verify all accounts and in their own words have "doubled down" on deleting fake accounts or non-primary accounts. One of the ways of doing this is asking for a mobile number.

It serves two purposes, to increase your security and also to share your phone number with your friends (which essentially removes the first advantage).

Of course Facebook can also potentially sell your number to a third party (any info you enter on FB becomes their property).
