Could be. Here are some criteria:

Does it promise an unverifiable future reward for believing in and propagating the contents?
Does it threaten an unverifiable future punishment for those who do not believe, or who ever stop believing?
Does it posit the existence of an invisible trickster who is responsible for all apparent evidence which contradicts the contents of this post?
Does it contain explicit instructions to spread it, in order to help others attain the reward, and avoid the punishment?
