This is an FYI that ModBar extension has been undeployed and, as such, its tables will be removed from all wikis.  See https://phabricator.wikimedia.org/T153033

It looks like this extension sprang some interest in the past [1] and there were some research projects about it. Please let us know (before August 7th) whether we should keep the tables for any reason.
