> LinkedIn has proven a fucking pain indeed, and that is why I am not active on it anymore.

Yep. There's another person in this thread trying to argue it away, but I've found LinkedIn to be a huge canary in the coalmine in these situations.

Someone who insists on maintaining an active LinkedIn profile but also isn't updating it with a new job isn't a red flag by itself (people just forget, obviously). It is, however, another piece of the puzzle.

If someone updates their LinkedIn and broadcasts their new job to all of their peers then I'm much less concerned.
