Does Xenforo provide tools that that act to impede or encourage user participation based on factors like "trust" and "reputation"?

As above...

Just trying to find ways to ensure that a forum isn't flooded with bad faith actors who provide low value and who ruin the experience for others.

There's add-ons, I think, for "reputation" but nothing really out of box.

The tool XenForo provides to impede bad users is the "Discourager". You can enable this in each users profile in Admin Control Panel , or via IP address under Users > User Discipline. I don't think you can make this work automatically based on reputation though.

Set the actual discouragement in ACP > Settings > Options > user discouragement.
