All my personal details on Facebook are (and have always been) false. My phone number is the number of a hotel in Monte Carlo. When Facebook nagged me to give them my mobile number for 2fa I ignored them. My friends thought I was crazy. I know it's not exactly gracious of me but feeling very self righteous right about now.

So you're stuffing it full of false data, but still connected to people who aren't stuffing it full of false data?

That seems like a lot of effort for no real payoff.

I happily pay for YouTube Premium, just to avoid ads. I wish I could do the same with Facebook

Do you still get tracked and your data collected if you pay?

Of course, but you don't get served ads.

Does your weed dealer provide the service for free? If you want to be treated as a $$$ paying customer start paying. Problem with social networks and $$$ is that network effects will not come into effect as not everyone will be willing to pay. There are actually ethical information dealers but they require you to pay them as you are paying your weed dealer.

So if I pay GM for a car they won't data-mine me? Just yesterday on HN we learned that this is not the case. Why do you think companies wont take your money and then proceed to sell your data anyway?

You should ask for your moneyback, because you're already paying in private data.

Isn't this it though, the engineers designing the ad targeting system at Facebook is linking the random emails you use as "catch all" to your main identity so you can be targeted specifically even though neither party has full knowledge of the linkage between your catchall email and your main identity email. This is facilitated by information that is not under your control. If facebook was able to design and build th…

Doing this seems like it would slow down an adversary with Facebook like capabilities for a handful of milliseconds.

I believe that for us to wait for our governments to have to make regulations around our privacy and data is overly optimistic. Since companies like Google and FB exist on a global market the only way to truly bring about any real changes is to take away the very thing that they're looking for, and that's our use of said services. As someone that works daily with the general public trying to educate them on the safety and use of their technology, I often ask what their feelings are on the subject of companies like FB and Google selling their data to anyone willing to pay for it. The response I get the vast majority of the time is that they aren't doing anything illegal so why would they care? My response to that is "Would you let strangers walk into your house and dig through your personal items?". Every time i get the same response. "Of course not!" Well in my mind this is no different. I've read a lot of suggestions on what we feel government should do to regulate these things but we need face facts here. Society is addicted to many of these services. The simple solution would be to just STOP USING THEIR SERVICES. There are alternatives to both of those services. We now know that the data being collected and sold has the potential of revealing information that could be used maliciously against us, and we complain about what's going on. But then many people turn right around and continue to use the free service. I truly feel that this isn't totally an issue with government regulation as much as it an issue with the vast majority of its users being completely addicted to it. If we want to truly make any kind of impact we need to take personal responsibility for these things. And not only that, but as people that are knowledgeable on these topics we need to educate those non-technical people around us just what it is they're giving up when they click Accept on their EULA's and privacy agreements. As much as I dislike what FB and Google are doing at the end of the day they are counting on the fact that the general public won't spend even 30 seconds reading these agreements. If users care so little about the fact that they're making a legally binding agreement why would FB and Google? Most are so concerned with getting access to whatever service they're attempting to gain access to that they just click the accept button with little or no thought about what it is they're agreeing to. Government can't be expected to do our thinking for us.

> A spokesman also told us that users can opt out of this ad-based repurposing of their security digits by not using phone number based 2FA. That's one way to encourage people to use 2FA App, I guess.

Note however that to enable any other type of 2FA you first have to give them your phone number. You can delete your phone number afterward, but it's too late, they have seen everything.

I'm not sure I understand what's going on here and the article doesn't really explain. What does it mean that they are "using your 2FA phone number"? It doesn't seem like they are texting ads to people. Are they just using the area code to determine where you live?

What's facebook's boiling point? My guess is they'll respond, they'll no longer use 2FA #'s for ads, the damage will have been done, and 99% of the population won't know any of it occurred. We'll repeat this cycle when a fresh revelation occurs months from now, as facebook continues to test how much they can leverage for more ad revenue.

But none of it is actually slowing FB down. Its biggest dip in value came from decelerating growth and spending to make FB more user-friendly, so there's a clear disconnect between shareholder incentives and those of the general populace.

On top of that, most people remain unaware that FB owns both WhatsApp and IG, and while the departures of their top brass have made waves in these circles, it's not a concern for most.

I don't see FB's dominance relenting any time soon, though I wish it would.

I really liked it when people downvoted me when I wrote that Google pushing for 2FA phone numbers is doing it to get your phone number. (they don't use it for ads but lately I don't trust them, also 6mo ago I removed my FB)

In the end I gave Goog even 2 of my numbers because I am scared as hell to lose access to my account. I got my Gmail account when it was in 'innvite only' so it is my main account for long time. Have to move out of it soon.
