Time and again, the literature refers also to more ``manual'' forms of quality control by editors using watchlists to keep an eye on articles they care about or even accidentially discovering edits made in bad faith~\cite{Livingstone2016}, \cite{AstHal2018}.
There is one mechanism though that is very ostentatiously missing from all these reports: edit filters.

At first, scientific studies on Wikipedia largely ignored algorithmic quality control mechanisms.
Their contribution to the encyclopedia and therefore their impact were considered insignificant. %quote?
This has gradually changed since around 2009 when the first papers specifically dedicated to bots (and later semi-automated tools) were published.

\section{Edit filters' role in the quality control frame}
+Let us review in this section what we have learnt so far and how edit filters fit in Wikipedia's quality control ecosystem.
+%TODO: explain table with text
+
+So, as shown in figure~\ref{fig:funnel-with-filters}, edit filters are crucial since they get active before any of the other mechanisms.
