Well, in a few days, at least. This is according to an announcement in the Steamworks group.

Seems like devs can opt out of this, but by default, this might help clean up some really crud-filled game forums. This is beyond just dealing with reports from other parts of game hubs (e.g. screenshots).

Valve claims they've also been expanding the global modteam. They also say they'll try to keep a light hand with moderating hubs so that devs have first dibs at deciding how to manage things. But they also say that a lot of devs have asked them for more moderating help, which motivated this change.

So yeah, I'm glad this is happening.
