1. My linkedIn connections include hundreds or possibly even thousands of people I have definitely never opted in to linking with. I don't know where they came from but I remove them at a rate of at least 10 or 20 per day and never seem to run out.
2. LinkedIn suggests connections derived from underlying data that are really scary from a privacy point of view. Eg for a while it kept recommending I connect with a person who I have literally no digital connection with whatsoever, no connections in common etc and the only way they could connect us is that we used to live at the same physical address. So it knows my address history and his.
3. I wish I could just automatically unconnect with anyone who reshares motivational posts by Oleg Vishnepolsky. This guys posts drive me absolutely crazy but the trite nonsense keeps infecting my feed because someone will reshare his thoughts about what makes a good boss or whatever. Just no more Oleg Vishnepolsky.
4. I have definitely seen the fake profile catfish thing attempted on LinkedIn. Presumably other forms of scams that have infested other social media are also growing.
