I thought I recognised the name - Bourbon Moth is the guy who faked a video of oily rags self-igniting to make a video to advertise fireproof bins for woodworking.
Writer Jack London's mansion,The Wolf House, that he was building up in Sonoma county was destroyed by a fire that investigators later attributed to the spontaneous combustion of oil-soaked rags in the dining room...
Uh, really? I haven't been following him for a while, so I don't absolutely know if you're wrong, but I absolutely can see him joking about it and maybe even taking it too far.
Never heard of either of these Youtubers but I've seen tons of cans of stains and such with warnings about potential self-ignition if left on rags in the wrong conditions...
