F*ck LinkedIn. You don't need it to get a job. I'm living proof. My profile has barely anything on it now.
They're amongst many companies who hate to provide minimal service to their "product." (Google, I'm looking at you.)
As for your ID issues, I had similar trouble when I lost my common sense and agreed to take a selfie while applying for an apartment in a new area. Several attempts to land thru perfect photo of my ID that they said wasn't verifiable (not sure why, folks, since my ID photo was nearly a decade old) and I gave up.
I would never do the same for a social media profile, so i recommend fighting back. Protect your privacy, ng friend, it's the last remaining bit of leverage you have.
