The signal to noise ratio on low-quality newspapers has to be very low and the Ghostbloods aren't omniscient; if you didn't know what you were looking for like W&W were, a random guy claiming that a tire manufacturer is producing nukes might be hard to take seriously. The Ghostbloods probably find most of their information elsewhere, possibly using some off-world technology like Breaths for spying purposes, likely just keeping track of important people. Note that they do seem to prefer quality over quantity in terms of membership, which I think would make checking every schizophrenic yelling about a conspiracy threatening the world somewhat harder.

Pretty sure this wouldn't work due to the fact that when you pull or push, an equal and opposite force is applied on the object that is pushing or pulling (We can see this very clearly in allomatic steelpushing and ironpulling). So for example when the machine would be pushing the other part upwards, it will fall down around the same height. Meaning that the center point between the two conjoiner fabrials will stay equal at all times when they push or pull each other without any support or external force. The machine would only fly as long as something is keeping it from applying the force that occurs when pushing or pulling on the bottom part, like the ground. This should generally be the case with all methods of pushing or pulling due to the newton's 3rd law. I'm not exactly sure if this would actually work then.

If BAM is actually a Bondsmith spren, the False Desolation could have happened due to her obtaining a bond. It's then explainable how the Sibling knew how to go into hiding, as they would have presumably felt another Bondsmith swearing their oaths. BAM is probably an Odium godspren imo, I doubt someone who would be so Connected to all the Shards would cause a Desolation.

A Fused touched by someone burning nicrosil would most likely just burn through their Voidlight resources. I doubt anything else would happen, since we do know that Fused often run out of Voidlight. A nicrosil caging would probably burn through all Investiture stored in the person affected by the fabrial? The dagger could have a nicrosil caging in order to drain the spren or person in it of Investiture. Since nicrosil is an external enhancement metal, it should work externally I'd say
