LinkedIn is a cesspool of scams now.
They know there's a high degree of fraud and they don't do anything about it. They don't care.
I've gotten tricked into sending my resume and talking on the phone with legitimate looking recruiters from Google, Netflix, Meta, OpenAI, Anthropic, etc, but LinkedIn does nothing about it.
It's become Facebook, too. I constantly see posts about the MAGA issue of the day.
