At this point, I would dismiss every image of anything that shared symmetry with any part of the camera taking the photo.

In the 90s there was a wave of diamond-shaped craft in Europe. All were taken by cheap disposable cameras with four-bladed aperture. The current trend now is fuzzy moving images. They are fixed points like stars and the "motion" and color changes comes from the digital camera's algorithm trying to make sense of a one-pixel signal from the ccd. (See flat earth videos claiming that stars/planets are actually spotlights.)
