This is a copy of Lupin's fantastic anti-vandal tool, with modifications.  Please do not
transclude it into your own .js; at times it may (for development reasons) work the opposite of 
the way you expect.  Copy it at your own risk; there is no warranty or support either express 
or implied.  Comments are welcome on the talk page.          Philip Trueman
 
This tool hits the RSS feed for recent changes every 30 seconds or so
and checks for common vandalism. It does not make a separate server request
for every edit.
 
Currently, the RSS feed is full of holes and so this may miss many edits.
http://bugzilla.wikimedia.org/show_bug.cgi?id=3942
 
N.B. Tim Starling says the bug is now fixed.  Also, note that the feed WILL have holes, because by default Special:Recentchanges excludes botflagged edits.
