 * What can we study?
   * Question: Is it worth it to use a filter which has many side effects?
+  * Do filters work the desired way/help for a smoother Wikipedia service or is it a lot of work to maintain them and the usefulness is questionable?
+  * Precision/Recall: False Positives? were filters shut down, bc they matched more False positives than they had real value?
+  * How has the notion of vandalism changed over time (not particularly computer sciency..)?
+  * What are disallow/block filters doing? Is it too great an intervention that drives new editors away? (Can we answer that?)
+  * Is it worth it to use a filter which has many side effects?
+  * What are discussions on filter patterns? On filter repercussions?
+  * What can we filter with a REGEX? And what not? Are regexes the suitable technology for the means the community is trying to achieve?
+  * GT is good for tackling controversial questions: e.g. are filters with disallow action a too severe interference with the editing process that has way too much negative consequences? (e.g. driving away new comers?)

+## TODO

+* How can we improve it from a computer scientist's/engineer's perspective?
+* What task do the edit filters try to solve? Why does this task exist?/Why is it important?
+* Why are there mechanisms triggered befor an edit gets published (such as edit filters), and such triggered afterwards (such as bots)? Is there a qualitative difference?
+* I want to help people to do their work better using a technical system (e.g. the edit filters). How can I do this?
+* The edit filter system can be embedded in the vandalism prevention frame. Are there other contexts/frames for which it is relevant?
