User blog comment:Cristina7/Introducing Discussions, a New Platform For Engaging Your Community/@comment-452-20160919170829/@comment-26213507-20160921174423

Exactly right. Our wiki already has had a "false mod" issue, where we promoted a visibly tame /d user, but they turned out to be too hostile and spammy for a mod.

Discussions is sort of in a limbo, where there is a few links to the main wiki but over all is disjointed. Most users there will occasionally browse the wiki but overall don't get far, and never edit.

In addition, even with careful moderation, we can't get everything, since the feed for recent discussion posts is tough to get to (and looked like a redlink, last time I checked). Spam posts are frequent, and I see tons of incorrect facts, which need to be corrected (but a lot of time the bad information is what catches on, prompting users to use that instead of the "corrected" info).
