Wikipedia is a paragon of virtue for that but from personal observations, they will become a fine case against "heavy handed moderation" one day if the Jennsaurus Files ends up in the media.
What we need is "due diligent moderation" instead of going into either extremes.
There could be a system which can address dead internet theory while avoiding "heavy handed moderation", by letting some users to verify themselves as humans by using Needemand's hand gesture verification solution. Presumably as others had put it, all accounts on any given platforms will then be divided into the categories of human-verified, unverified/ambiguous and bots.
