Is it just me, or do you seem to never hear from anyone whose belief in a conspiracy theory is confined to a single topic? That is, if they believe that Apollo was a hoax, it's almost certain that they subscribe to many, if not all, of the popular CTs around.
And a sort-of related question: how much do you ever seem to hear about conspiracies that aren't centered around the government of the USA, or at least directly related, such as the joint US-USSR space travel hoax?
Edit: I have seen that Anders has questioned the investigations of, well, pretty much every maritime disaster of the last hundred years as being a cover-up of some kind, but this is his rice bowl and I don't recall seeing them discussed anywhere else.
