 In order to be able to answer them, various Wikipedia's pages, among other things policies, guidelines, documentation and discussions, are studied in chapter~\ref{chap:filters} and filter data from the English Wikipedia is analysed in chapter~\ref{chap:overview-en-wiki}.
 But first, chapter~\ref{chap:methods} introduces the applied methodology.

 Following insights about temporal trends were uncovered:
 %Firstly, the overall number of active edit filters stays the same over time due to the condition limit.
