Subject: [Wikitech-l] Abuse Filter extension activated on English Wikipedia
To: Wikimedia developers <wikitech-l at lists.wikimedia.org>

I am pleased to announce that the Abuse Filter [1] has been activated
on English Wikipedia!

The Abuse Filter is an extension to the MediaWiki [2] software that
powers Wikipedia allowing automatic "filters" or "rules" to be run
against every edit, and to take actions if any of those rules are
triggered. It is designed to combat vandalism which is simple and
pattern-based, from blanking pages to complicated evasive page-move
vandalism.

We've already seen some pretty cool uses for the Abuse Filter. While
there are filters for the obvious personal attacks [3], many of our
filters are there just to identify common newbie mistakes such
page-blanking [4], give the users a friendly warning [5] and ask them
if they really want to submit their edits.

The best part is that these friendly "soft" warning messages seem to
work in passively changing user behaviour. Just the suggestion that we
frown on page-blanking was enough to stop 56 of the 78 matches [6] of
that filter when I checked. If you look closely, you'll even find that
many of the users took our advice and redirected the page or did
something else more constructive instead.

I'm very pleased at my work being used so well on English Wikipedia,
and I'm looking forward to seeing some quality filters in the near
future! While at the moment, some of the harsher actions such as
blocking are disabled on Wikimedia, we're hoping that the filters
developed will be good enough that we can think about activating them
in the future.

If anybody has any questions or concerns about the Abuse Filter, feel
free to file a bug [7], contact me on IRC (werdna on
irc.freenode.net), post on my user talk page, or send me an email at
agarrett at wikimedia.org
