I would like a status called "no source" or "source challenged" for answers with questionable sources. Something like this already exists partially for no source and unacceptable source, but a direct challenge of alleged scripture doesn't exist. And this feature seems to be system/mod generated and is selectively implemented by the mods. This right should be given to all and implemented transparently.
posters should be given a fixed period of time to answer factual challenges, and if they don't respond their answers should be deleted.
For sources allegedly taken from the internet - A CLICKABLE LINK SHOULD BE MANDATORY.
