Most people don't check LinkedIn regularly like they do other social media. It's a place to put your work experience and to find jobs. So no one pays that much attention to what's on the home page anyway.

You can delete your account if you don't plan on using LinkedIn again. I think that's overkill. Just move on and act how you want to portray yourself on LinkedIn (which often becomes not using it at all). No one will be the wiser.
