To be fair, most of those comments are from folks many of us from the site have never even heard of, and from practically everywhere around the internet, including Youtube. The comments are just that, we only put the information out there. In fact, we try to moderate our chat to keep things like alien abductions, hoaxes conspiracies and UFOs from being mentioned, because it detracts from the serious part of actually making space more widely known to the masses. Intelligence and curiosity are both welcome things to spacevidcast. Trolls and spammers however, aren't so warmly welcomed.
But to be fair and respond to your reply, if you don't think we actually landed on the moon, please remember, we did do it 6 times. We went to the moon 9 times. Why would we fake it nine times? Why haven't any of the 500,000 or so NASA employees (edit; of that time) come forward to claim it as a hoax, even now as they're in their 70's and 80's? Why didn't Russia even try to call our bluff, even when they hated us? It really is more difficult to fake these missions than it would be to actually do them.
Oh yeah, don't forget that the Lunar Reconnaissance Orbiter from the US, as well as the Indian chandrayaan-1 got hi-res pics, even so much as spotting the footprints and rover tracks. And then there's that retroreflector left up there after we set it up that we still use to this day for measuring distance to the moon. The Mythbusters even did a full show about trying to replicate the landings, to determine if they were faked or not. Given that the Mythbusters are in fact special effects experts, for them to try to turn it into a hoax and fail says a lot in itself.
