They know your location and proximity to other facebook users.

Re: Facebook Doesn’t Tell Users Everything It Really Knows About Them
#12I've been saying this for years. It's pretty clear that if Facebook told regular users just how much they knew, those users would be seriously creeped out (though, these days, probably not creeped out enough to do anything about it). I expect that another example of this would be the ability of their facial recognition system and the breadth of the database behind it.
Users are Facebook's product, and they should expect to be treated as such. The Facebook site and associated services are just infrastructure designed to a) collect information on users and b) give advertisers optimal access to those users.
edit: also, obviously, Facebook is not the only company engaged in this sort of thing. It's all around us.

#13You can replace "Facebook" with thousands of other companies. Everyone is doing this because the cost is low, its easy, and the return is massive. The sole service my roommate's company does is match your customer with data about them from countless other sources. If you want a peek into a small section of this type of data, go build a facebook ad. You can see all the targeting options. You can upload a list of email…
With so many data sources, it should be easy to find proxies for protected classes (race, sex, etc). Indirect discrimination was (and still is[2]) used to enforce racial segregation ("redlining"[1]). Facebook was recently caught[3] enabling direct discrimination. I wonder if your roommate cares that his company is probably doing the same thing indirectly.

#16This is outrageous. Why is the onus on a user who never gave permission to a data broker in the first place? They deal in digitial domain when it comes to selling your data when it comes to consumers rights and concerns they operate exclusively via snail mail?
Don't expect this to change any time soon. These brokers have the US Electorate in their pocket. Bought and paid for.

If you or one of your contacts uploads their address book then your friendship/connection can be inferred from the emails now in their database.
I'd guess your client has messenger installed if you didn't install it.

#18I know it sounds crazy now but people also thought no regular person would ever need a personal computer. IMO the next computing revolution is in personal appliances with OS (but black box, plug-n-play to regular foks) that serve up usable voice recognition and other SaaS stacks that replace the "free" data black holes currently in use.

The most common source of those suggestions is phone contacts. Anyone using the Facebook (or Instagram) app is sending them a copy of their entire address book to be used for network mapping purposes.
