So I deactivated, and all the way permanently deleted my Facebook profile back in must’ve been '22 ior '23, and I’m aware of the spyware nightmare it poses but unfortunately I’m thinking I need to set up a new profile in order to use their marketplace, I have a certain little something of decent value that I’m looking into all feasible channels of reselling it, be it locally or shipping it thru some site or service. Obviously this hesitantly so, I hate Facebook and want to go about this in the most op-sec conscious way, or as much as possible for an armchair noob like me who hasn’t quite learned the way around the whole root or kernel or anything crazy. Talk to me in college drop-out, duckduckgo terms. This is a brand new android phone with old SIM is that helps.
Check first what information is required to sign up again with a new account. Like the other commenter said, they might be asking for actual ID now just to sign up. In that case, just sell somewhere else. If you are able to sign up without providing any personal information, use facebook on a browser only. Firefox with uBO and facebook container. Use an email specifically made for that account and don’t use it anywhere else.
