+Since edit filters run against every edit saved on Wikipedia, it is generally adviced against rarely tripped filters and a number of alternatives is offered to edit filter managers and editors proposing new filters.
 For example, there is the page protection mechanism that addresses problems on a single page.
 Also, title and spam blacklists exist and these might be the way to handle problems with page titles or link spam~\cite{Wikipedia:EditFilter}.
+Moreover, it is adviced to run in-depth checks (for single articles) separately, e.g. by using bots~\cite{Wikipedia:EditFilterRequested}.

-"There is a bot reporting users tripping certain filters at WP:AIV and WP:UAA; you can specify the filters here."
-\url{https://en.wikipedia.org/wiki/User:DatBot/filters}
+So far we have juxtaposed the single quality control mechanisms and compared them separetly.
+It is however worth mentioning that they not only operate alongside each other but also cooperate on occasions.
+%TODO see Geiger's paper (banning of a vandal?) where the process of tracing the same malicious editor throughout Wikipedia and reverting their eidts with various tools (and issuing them warnings) leads to the (temporary) block of the editor
 
-* consider collaborations filters/bots (e.g. MrZ Bot which puts editors found on the abuse log often on the AIV noticeboard.) are there further exampled for this kind of collaborations?

 * an idea for the presi/written text: begin and end every part (section/paragraph) with a question: what question do I want to answer here? what question is still open?
 * How many of the edit filter managers also run bots. How do they decide in which case to implement a bot and in which a filter?
 * Why are there mechanisms triggered before an edit gets published (such as edit filters), and such triggered afterwards (such as bots)? Is there a qualitative difference?
