Oh good. Facebook gives advertisers your two factor authentication phone number.

<< They found that when a user gives Facebook a phone number for two-factor authentication or in order to receive alerts about new log-ins to a user’s account, that phone number became targetable by an advertiser within a couple of weeks. >>



It's beyond me why people still can't understand that phone number IS NOT A FACTOR at all. It's just a way to bind your account to your identity.
So the rule of thumb here is simple: some site tries to pry your phone number as a second factor "for your security"? Fuck this shit.
