[Wikimedia-l] Has the underlying level of edits risen or fallen since the Edit Filters came in in 2009?

The question can't really be answered without knowing what you want to 
achieve; I'll start from the end.

Usually we consider the number of active users, which is less affected 
by this. Editing activity should be measured using 
http://stats.wikimedia.org/EN/PlotsPngEditHistoryAll.htm which allows to 
check for unreverted edits (just updated by Erik after a few years it 
had been dormant).

If your aim is measuring the impact AbuseFilter in reducing patrolling 
efforts, then it's another matter. I've requested some reports in 
https://bugzilla.wikimedia.org/show_bug.cgi?id=42359 : there are already 
some DB queries but we lack a visualisation.
You can also use https://meta.wikimedia.org/wiki/Abuse_filter to find 
what wikis used (or not) the abuse filter and how, before it was enabled 
by default on all wikis.
