You must trust your own instincts. The majority of supposedly channeled information is deliberately generated by humans looking to either disinform the populace or generate income. Those looking to disinform do so for a wide variety of reasons. Some disinformation is to put forth a message they wish the populace to believe. For instance, if some in your government wished the populace to believe that they have cut a deal with aliens, so that immediate conquest by rampaging aliens had been held at bay by negotiating skills, they would create a false channel to this effect.
Some disinformation is to counter a message unwanted.
For instance, if some humans wanted the populace frightened enough of aliens that they would cling to the establishment for protection, and an alien group, such as ourselves, reported that humans can repel unwanted visits from aliens just by taking a firm stance, these humans would create a false channel reporting otherwise. In all cases where a fraud is being perpetrated, the false channeler must create a massive amount of details, or a single message as a standalone looks suspicious. Since none of this is provable, and the humans generating the fraud know they won't be challenged unduly, they wax poetic. This situation is not an alien issue. It is a human issue.
