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?
I’ve been fairly parsimonious with my information for a fair while - I don’t use my real name online except when unavoidable for payment etc, don’t put photos of me anywhere, use social media (other than Lemmy, and I’m not very social on here really!) and I think I have fairly good habits to keep information and habits separated. I alternate between using FF, Librewolf and Mullvad browser for different things, don’t reuse usernames/id’s, use a VPN router at home and have VPNs on my mobile devices, email masks and relays, and where possible pay with virtual cards etc. I think my most unique identifier, last time I checked with the EFF site, was the size and resolution of my screens. I’m not really sure how much data there is to collect about me past the mundane, as I don’t really associate with anyone in the real world online, and almost exclusively use signal in the real world.
