I have a feeling I know the answer, but thought it worth an ask, so here goes - I’ve not used FB in years, and generally try to keep fairly private online (Mullvad, librefox, etc) but I’ve found I’m missing out by not being able to use FB marketplace. If I set up a fresh account, and don’t use the social side of it at all, is there a fairly safe way to use Facebook? In a container, or in Mullvad browser with nothing else open? Or an an extreme, in a VM?
regardless of what measures you set up, they’ll still be able to collect a bunch of data based on what pages you visit their service, which posts do you spend more time looking at and which you scroll past, and so on.
It’s worth noting that Facebook regularly collects information and builds profiles about people who are not users (or are users who but aren’t logged in). The average user would be surprised what a company like Facebook can put together on individuals who have never made an account.
