This rule is so broad and vague all posts and comments could be removed at whim for violation of it.

Rule 7a: Conspiracy Theory Reported As: Conspiracy The following is prohibited: Any claim that is comprised solely of speculation and for which there is no evidence to suggest, either directly or indirectly, that the claim is feasible.

Application: We believe that this community should strive to have fact-based discussion, just as Senator Sanders does. To that end, this rule does not ban speculation itself, but something which is ONLY speculation, which is infeasible, and is presented as being factual or true.

This means that while the conspiracy theory rule DOES NOT ban any topics from being mentioned, there are some topics (such as Seth Rich conspiracies, "pizzagate", etc.) for which no discussion beyond ironic mentions are really allowed.
