That's cute, but if people truly believed there was any doubt that he did it, there wouldn't be the wave of support and enthusiasm he unwittingly created.
See, that's where you're wrong. If people doubt he killed the dude, he's got support due to being martyred so the capital class has a scapegoat. If he killed the dude, he's got support because he did what tons of us fantasize about when we get the bill for insurance and the bill from what they refused to cover.
No matter what side you fall on, short of deepthroating the boot, you've got reason to support him.
Dude in iT, never had that problem and even doubled my salary through linked in. Anytime I actually interact with a recruiter I lay down my bare minimums and won't even bother responding further/block if they can't hit that.
That said, LinkedIn is a shit hole not worth touching more than once every couple of years if you're not looking for a gig. I don't even really interact with people I actually know in there because the platform is terrible and 90% of public posts are from sociopaths who despise work life balance.
