The most unsettling part is in Facebook's response: “We’ve heard that when accessing their information from our Download Your Information tool, some people are seeing their old videos that do not appear on their profile or Activity Log. We are investigating.” Who wants to bet against their investigation being “how to keep users from seeing it.” Anyone?

It's no bet. The investigation results in a ticket for another intern to add "WHERE deleted = 0" to the download tool.

Earlier quoted context omitted.

GDPR is intended to at least force service providers to give folks the right to be forgotten which compels providers to delete data. While it's own Europe, it's difficult to comply without just making general decision about honoring these requests.

Actually, GDPR only requires that any links from the data to the user should be destroyed, so that you can no longer figure out who created the data. This means that a lot of data will be left. And realistically I think that a lot of it will remain identifiable, just like anonymized data can be traced back to real users pretty easily if you have enough data points.

Pretty certain that videos and photos count as personally identifiable information that have to be deleted.

One fascinating outcome of all this fallout is that there's now a readymade excuse to stop using Facebook.

My personal observations are that a good number of people have felt 'fatigued' by Facebook for a very long time, but were also unsure of how best to extricate themselves without incurring a social penalty.

But now there's an impetus that most people can understand. I'm not sure about how many people will move away or how quickly it'll happen, but the network effects Facebook capitalized on can also work in reverse: if you have just one or two very vocal privacy proponents in a friend circle pushing to get off the platform. One group I'm in recently migrated to Telegram for this very reason.

This reminds me of the long conversations that I used to have with family members and friends several years ago. With their continuous requests to create my own Facebook profile so I can keep in contact with them and with their activities as well as to share my whereabouts. I always used the same argument to reject these suggestions — "I don't want Facebook to have too much data about me, more than the data that you…

"I am sure that the deletion of media files in services like Facebook has never meant to be absolute." This is very common, I'm sure. There should be a way to request or a right to request permanent deletion, by law, of one's data on site like Facebook. That said, once something is on the internet, anyone can and will archive it (see https://www.reddit.com/r/DataHoarder/ ). Closing an account, however, should imply p…

Obviously I'm not privy to the details of this particular requirement, but I'm fairly certain that very few, if any, of our videos actually go away when we delete accounts. (Or even when we delete the videos themselves.) I think this because I've seen images from SMS texts, instagrams, snapchats and things of that nature used in court cases. So law enforcement must have access to that stuff somehow? But, again, I'm not privy to the technical or legal mechanisms they use to make that happen. All that said, I have seen images from services like these in court cases. And defendants have CLAIMED that they had deleted them. (For whatever value of "deleted" exists on the given service.)

So I'm wondering if the services actually have some sort of archiving requirement for law enforcement purposes? Maybe for a certain number of years, they have to save your data or something like that?

If there's anyone who would be familiar with the legal obligations of these services vis-a-vis data archiving I'd be really interested in hearing more about what we should reasonably expect from these services in terms of deletion etc?

> expecting a non-tech-savvy person to understand how data moves around the Internet

Then we - the people that do have the necessary technical knowledge - have a duty to teach them what they need to know. This isn't necessarily "how data moves on the internet". Yes, this can be difficult and tedious, but understanding the risk profile for data/networks is increasingly important as networks become involved in everything.

> they ultimately don't care

Again, it's our duty to teach them why they need to care. This probably shouldn't involve a lecture on networking or data analysis, but instead tailoring an explanation to their personal situation and knowledge.

I’m not a GDPR lawyer, but I do live with one.

My understanding is that an image is by itself PII, regardless of whether or not it has any additional information associated with it. I don’t think there’s a way to retain images without contravening GDPR.

> I am sure that the deletion of media files in services like Facebook has never meant to be absolute. Many of my colleagues believe the same thing that I believe: Facebook and other services do not actually delete data, they just mark it as "deleted" and purge it only if they need the space. This is a dumb conspiracy theory. Facebook has made plenty of public statements that say otherwise, and there's a whole team t…

First lesson in DB class: do NOT delete. Just flag.

I can give you plenty of statements about how I'm Santa Claus though.

Huh. So now I'm starting to think: what if I purposely recorded thousands and thousands of meaningless video? None of my friends would ever see them since I never published them, but Facebook would use up hard drive space storing them. What if a lot of people did that? Suddenly Facebook's cost for hanging onto all these videos would become quite high with no value in doing so. Anyone feel like making a website to hel…

You should upload random-pixel uncompressible videos and delete them over and over again. It not only increases storage cost but makes the profile SNR very low.

There are general-strike level attack surfaces on these networks, but people don't really care that much.

You think people could organize better than against Trump ? seems unlikely

Trump has many supporters(not me). I don't think any facebook users particularly like facebook, it's just where "everyone" is.

Exactly this.

Who even supports FB?

The media? No, they hate them because they took all their ad revenue.

Republicans? No, they hate them for the censorship controversy that happened a year or so ago, and because it is full of ultra left wing silicon Valley types.

Democrats? No, they hate them for the whole Cambridge analytica, Russian data thing.

Facebook has made a lot of enemies, and there really isn't any sort of constituency that SUPPORTS them.
