It's pretty scary all the horror stories one hears on HN along these lines. I wish some regulation would be imposed requiring some sort of approximation of "due process", so to speak, when this happens to people.
Anyway I've never felt it's a requirement to have a LinkedIn profile to get hired as a developer, so the post as a whole is strange to me.
Why do you think this? Misguided/buggy/flawed algorithmic bans seem quite commonplace these days, and increasingly companies have too few humans to even respond to the actual inquiries that result from them, much less review every instance of it happening.
It's possible, but I felt like voicing the general concern regardless because at least some of these random permaban stories seem to be true.
(Sorry it seemed too timely not to make the joke!)
Hope you'll be able to resolve this, or find another way; I do agree that LinkedIn is a monopoly here and you should have recourse as an individual. Scary how Kafka-esque our techno future has become.
