- Renaud 10y agoBut Facebook will not know it's me because FB doesn't have my number. At worst, all FB know is that some people have my Whatsapp number. That doesn't help FB serve targeted ads to my FB account.
- eric_the_read 10y agoFB is constantly popping up a message to me saying, "Is (xxx) xxx-xxxx your phone number? Confirm it now to secure your account" despite the fact that I have never given them my phone #, nor ever used Whatsapp. I'm sure they know perfectly well it's you, they just aren't (for whatever reason) doing anything about it yet.
