I've seen a lot of mentions of pictures showing the curvature of the Earth being faked. If you're truly passionate about this conspiracy why not easily tackle it by taking your own photos or, better yet, video? The materials needed wouldn't be too expensive; though I'd argue no price is too expensive to prove a point like this.
All you'd need is a proper balloon, GoPro, antenna, and some sort of insulated housing. High school kids do it for science fairs. They tend not to get images of an infinite Earth or any sort of ice wall.
(Also, but unrelated, is this entire site just designed to troll people? Am I just not in on the joke?)
