See e.g. [http://de.wikipedia.org/w/index.php?title=Spezial:Missbrauchsfilter-Logbuch&wpSearchFilter=4]: There is a log entry
:"2009-06-16T21:30:44: 90.136.148.123 [...] triggered filter 4, performing the action "edit" on [[:de:Stempeltechnik]]. Actions taken: none; [...]".
Although rule #4 does not disallow changes (it just logs them), you can't see the change of [[:de:Stempeltechnik]], when you have a look at [[:de:special:contributions/90.136.148.123]]. So what happened there? I gave some more of these examples at [http://en.wikipedia.org/wiki/User_talk:Werdna/Archive_1#63364096679].
