Maybe they wanted to fabricate a ghost video. It's still a hell of a lot more plausible than any supernatural explanation.
And yet... what if they didn't? What if this is really something they have no explanation for and just caught on camera?
The thing is, MR should have ruled out all mundane explanations before claiming a supernatural one. Then we wouldn't have to bring them up.
If he doesn't want to, or can't, do that, he shouldn't post the thread.
We are actually doing his work...
If that's how we want to run things... then we may as well not have this section at all *shrug*
