 \section{Edit filters on the English Wikipedia: State of the art}
 
-* how many filters are there (were there over the years)
-* what do the most active filters do?
-* get a sense of what gets filtered (more qualitative)
-* has the willingness of the community to use filters increased over time?
-looking at aggregated values of number of triggered filters per year, the answer is rather it's quite constant
-* how often were (which) filters triggered
-* percentage of triggered filters/all edits
-  * break down triggered filters according to typology
-* percentage filters of different types over the years
+\textbf{Interesting questions}
+\begin{itemize}
+    \item how many filters are there (were there over the years)
+    \item what do the most active filters do?
+    \item get a sense of what gets filtered (more qualitative)
+    \item has the willingness of the community to use filters increased over time?: looking at aggregated values of number of triggered filters per year, the answer is rather it's quite constant
+    \item how often were (which) filters triggered
+    \item percentage of triggered filters/all edits; break down triggered filters according to typology
+    \item percentage filters of different types over the years
+\end{itemize}
+
+\textbf{Questions on abuse\_filter table}
+\begin{itemize}
+    \item how many filters are there altogether
+    \item how many are enabled/disabled?
+    \item how many hidden filters? how many of them are enabled
+    \item how many are marked as deleted? (how many of them are hidden?)
+    \item how many global? (what does global mean?)
+    \item how many throttled? (what does this mean?)
+    \item how many currently trigger which action (disallow, warn, throttle, tag, ..)?
+    \item explore timestamp (I think it means "last modified"): have a lot of filters been modified recently?
+    \item what are the values in the "group" column? what do they mean?
+    \item which are the most frequently triggered filters of all time?
+    \item is it new filters that get triggered most frequently? or are there also very active old ones?

+\textbf{Number of unique filters that were triggered each year since 2009:}
+owing to quarries we have all the filters that were triggered from the filter log per year, from 2009 (when filters were first introduced/the MediaWiki extension was enabled) till end of 2018 with their corresponding number of times being triggered:
+\begin{table}
+  \centering
+  \begin{tabular}{l r }

+    Year & Num of distinct filters \\  
+    \hline
