LinkedIn locked me out of my own account. The only way back is through Persona — a third-party service that wants a photo of my passport, a scan of my face, and a recording of my movements (liveness detection: turn your head, follow the dot, so a still photo can’t stand in for me). The stated reason: “unusual activity.” The real reason, of course, is big tech spearheading a movement toward absolute control over people.
If you’re a salaried employee who isn’t currently looking for work then this might be an option. If you’re a consultant who relies on networking then LinkedIn has a near-monopoly. If you’re not on it then potential clients will assume there’s something wrong.
