I'm surprised people didn't know this... this has been happening for at least 4 years through custom audiences. An advertiser can upload a list of mobile numbers or email addresses to target people.

The reason I never give fb my mobile is if you use a pseudonym account, it will suggest your profile as a friend to anyone who has your mobile in their phone contact list (eg ex-partners, stalkers, employers, drug dealers). Found that one out the hard way.

I know Zuck wants me to preemptively upload my nudes, but still.

Facebook gonna Facebook. It's long past time to consider regulation of an ethically bankrupt corporation.

Phone numbers were not a secure 2FA anyway, and I've been using the TOTP alternative since it's been available... but I don't really see a problem with them using whatever to show "more relevant ads", if you don't want ads just use an ad blocker.

Can you link me the Ad Blocker for text messages?

What if the more relevant ads are robocalls like in this case?

Who is still answering phone calls on their cell from numbers not in their contact book? If you call me and you're not in my phone my phones just dumps you direct to voicemail.

Not excuse this behavior in the least, but robo calls in general are a solved problem for me.

"four months ago" they stopped requiring it for 2FA, that's the time GDPR came in.

I wonder if Facebook acts differently for European users?
