LinkedIn was doing this to me, too. But then I randomly was able to log on again. I wasn’t able to for months and thought it was ridiculous that they were asking for my ID.
You can try logging in on an IP address you previously logged in on. Then, delete your account ofc.
At this point, I don’t know why Republicans don’t outright just say they want people who they see as less than them suffering and/or dead. That’s their only consistent political view.
