+These tables, along with \emph{abuse\_filter\_log} and \emph{abuse\_filter\_history}, are created and used by the AbuseFilter MediaWiki extension~\cite{gerrit-abusefilter}.
+Selected queries have been run against the \emph{abuse\_filter\_log} table as well.
+Unfortunately, currently the \emph{abuse\_filter\_history} table is not exposed to the public due to security/privacy concerns.
+We hope to be shortly able to access a view of this table in order to conduct historic inquirements.

+The schemas of these tables can be viewed in~\ref{fig:db-schemas}.
