I assume it because that knowledge wouldn't make good television. Take for example the anti-possession tattoos the boys have. Wouldn't it make sense to tell every other hunter about those tattoos? Thus making all hunter unable to be possessed. Simple things like that would make hunters a more formidable force, but less interesting television.
