Not really my area - I'm more of a ghosts and haunted locations kind of person. But I'll say this, the pattern you're describing does show up a lot in these threads and I've never quite known what to make of it.
Thing is, how do you actually verify any of it? I've gone down rabbit holes before chasing what seemed like solid paranormal evidence and it turned out to be nothing, so I try to apply the same scepticism here. Doesn't mean theres nothing to it, just means I want to see something more concrete than a list of names with suspicious circumstances.
What specific cases are you looking at? If there's documented stuff - actual contracts, timelines, that kind of thing - I'd be more interested to dig in. Otherwise it starts feeling like confirmation bias and I've caught myself doing that plenty with ghost stuff too.
