Facebook Is Giving Advertisers Access To Your Shadow Contact Information

I think platforms like Facebook depend on being "cool" over some demographic. Then other demographics adopt it, time passes, other demographics grow tired of the same old Facebook look their parents also used, and Facebook starts to die. We've seen this as well with other social networks like hi5, myspace, that once dominated entire continents as the preferred social website. Of course they are smart and competent people so they will try to prevent it, and it seems to have lasted longer and left a bigger mark already, but still; I'm sure a lot of people around the world already share the sentiment of "not doing anything on FB", and just keeping it open for messenger chat.

Are you hinting that FB advertisers are throwing 50 billion (expected 2018 revenue) at ads that are poorly performing? Obviously that is not correct, the result of all this detailed targeting is campaigns that are performing very well for experienced marketeers.

You can personally decide not to use Facebook, which is good. But you can't convince everybody to do that. So if you or your family members do use Facebook, at least install an ad blocker for all of them.

Not for privacy, but to deny them revenue. I block Google ads on every single site I visit, period. I don't care if the advertising is non-obtrusive. If it's being run through Google, part of that revenue is going to fuel Google's tracking. I support creators directly instead. And if creators refuse to give me a way to support them, that's not an excuse to expect me to contribute to Google's bottom line.

Huge props to the people who are working on blocking trackers and protecting privacy. I'm very glad they exist, and I don't think their efforts are worthless. But, it is currently a losing battle to fight these companies on the privacy front, because the tracking model is so profitable that they will always be pushing more resources into it than we are. Collectively, the people fighting for privacy don't have enough resources to win.

But there's an easy, completely legal solution to that problem; the one thing companies haven't figured out how to get around is ad blocking. And a good ad blocker will block even native ads. For a company like Facebook, all of this boils down to getting you to click on ads. If enough people target that chokepoint, then the advertisers will start pulling out of the system, and there'll be less financial incentive for these companies to undermine people's security and privacy.

And we have evidence that this works. Even Google, which is the powerhouse for getting their ads to actually show up, is starting to devote more resources into trying to figure out how to stop mainstream people from installing adblockers. That's where all the autoplay stuff came from, that's where the acceptable ads initiative came from. They desperately want your roommate to say, "I'm not going to mess around with these weird Chrome extensions or whatever, that's too complicated. Chrome blocks this stuff itself, anyway."

Install adblock on every browser you get access to, tell ordinary people who aren't on HN to use it, and let the advertising industry kill itself. Make it very obvious to companies that buying ads on Facebook is a complete waste of time because even non-technical users just won't see them.

The phone number isn't for your protection (it's actually really terrible for 2FA), it's for Facebook's protection. It's an anti-bot mechanism to require a unique phone number for each account, or no more than 5 accounts per number or so.

They also refuse VoIP numbers for authentication.

This. Though I will say, in my opinion tech companies are more or less wild animals we pretend are domesticated.

Nothing is free.

Facebook continues to do good for people. Twitter as well. These are invaluable communication channels for many people.

I imagine this problem will get fixed about the same time my physical spam mail stops arriving. I'm not holding my breath, given that I can _say_ something to my wife in the privacy of our own home and get a cold call or physical mailing about it a few weeks later.

I try to encourage people to pay for the services they believe in. Whether you love or hate Microsoft for $6.99/mo you can get Office, (decently private) email, cloud storage, and Skype. Hate Skype? Don't blame you but from there you can get a phone number that you can give out and keep your personal number just for family/emergencies.

This sends a powerful message to folks trying to build a better mouse trap. It is _very_ hard to produce a free service that competes with these folks but if we show we're willing to pay for privacy then maybe we'll start to see competitive innovation in that space again.

Now that I have a family it inspires rage that my phone rings constantly from spammers and I might ignore a call that's time sensitive and important.
