They have very personal information available about you.
But Congress doesn't understand the problem - or the power - of Facebook any more than most of the rest of us do.
Technically, Facebook's users can turn off targeted advertisements or disable sensitive features such as image recognition in photos. Inevitably the new age appears somewhere in the many ensuing comments. "They are already having conversations about how they cannot only make sure their current systems better protect user privacy and autonomy, but how artificially intelligence systems they are using can have ethical alignment built in by design", said Ms McEvoy. "Here is Facebook knowing this research and deliberately trying to get even younger kids to use their platform ... the last thing that kids need is to normalize this idea that relationships should take place online, that relationships should take place through a commercial product". The social media company also acknowledged that "malicious actors" scraped information from the public profiles of practically its entire base - more than 2 billion users.
But it was also Graham who asked one of the most important questions of the five hours' worth of grilling that was set to continue in the U.S. House on Wednesday - whether Facebook is a monopoly.
The Guardian pointed out the absurdity this way: "Two tweets, one each from Sens".
According to Oosthuizen, the court found that he had "used disgraceful and racist language constituting hate speech, he did so in his capacity as a police officer, and he did so on a quasi-public forum accessible to potentially thousands of Facebook users... there is no doubt that dismissal was a fair sanction".
"Drug sales are strictly prohibited on Facebook", the Facebook tweet said.
The hearings generated much heat but little light, as was predicted by Zeynep Tufekci, a professor at the University of North Carolina and one of the keenest observers of Facebook and our evolving digital landscape.

It's not Zuckerberg's fault that he has suddenly been deemed on the wrong side of history, but the Cambridge Analytica blowup is bringing a useful spotlight on the most sanctimoniously self-regarding large company in America. It's the price of using Facebook. If so, expect to see Zuckerberg answering many more questions, most likely surrounded by a small army of lawyers. Most people don't seem to think it - and the other giant social networks - will fail.
Facebook has admitted up to 2.7 million people in the European Union may have been caught in the scandal.And last week the European Union had said that its justice commissioner, Vera Jourova, would hold phone talks with Facebook's chief operating officer Sheryl Sandberg to discuss what the company is doing to address the breach, which may have affected 87 million people around the world. Can Facebook track browsing activity after a user logs off? Or, if you gave your email address when you bought a pair of slippers from Land's End, you might get an ad for an upcoming slipper sale, since Facebook has your email address too.
Compassion, corporate social responsibility, thought leadership... all those things went out the window a long time ago for Mark Zuckerberg.
The decision came as Facebook CEO Mark Zuckerberg appeared before the US Congress twice in less than 24 hours, apologising for the data breach scandal involving British political consultancy firm Cambridge Analytica.Social networking giant Facebook has chose to stop funding a campaign that aims to defeat the California Consumer Privacy Act. We can also all read the fine print, especially the lawyer-speak that might as well be in Swahili.
Facebook founder Mark Zuckerberg left himself some wiggle room in testimony this week when he said, "I believe that all of your information is in that file". I appreciate the apologies.
