Affiliates Add-on: Classifieds?

When viewing the add-ons for Affiliates, there is a Classifieds add-on that states the plugin is not installed. However, you guys do not have a Classifieds plugin and I am curious to know what plugin this add-on is referring to as I am interested in getting it set up.

EDIT: Also curious about the Directory add-on as well as it also doesn’t give the name of the plugin and the Documentation on Affiliates does not cover either of these options (only has the WPMUDev plugins on doc).
