New subject: [Foundation-l] Fw: Strike against the collection of personal data through edit links

5 Feb 2012

Hi Brandon, thanks for the explanation, but wouldn't it be easier to just
analyse edit summaries? If you edit by section the edit summary defaults to
start with the section heading.......

        (This may not be 100% accurate; the person who knows most about
 this is
 on vacation, but I'll try to explain to the best of my understanding.)

        Those weird URLs are part of a clicktracking process.  It's a test
 to
 see how people go about editing the page *most often* (by section, or by
 edit tab) and further to see how effective various calls-to-action (such
 as those given by Article Feedback) are.

        The longevity of the data isn't something I can comment to but I'd
 be
 surprised if it lasted even 3 months.  I do not know if there are
 identity markers connected to them but I wouldn't be surprised.

        To that end, the data is only useful in roll-ups, and wouldn't be
 something published anywhere except in aggregate.

  MZ is correct:  3 months is the purge for
Checkuser data.

 As to the rest of it, Diederick van Liere, our resident guru of data,  will
  be checking into this, and will confirm back when
we know exactly wht is
 intended by the devs for that data.  I will say that generally speaking,
 the Foundation prefers to maintain the minimum data possible for the
 shortest period of time.

 Thanks,
 pb

ser.php?revision=106556&view=markup>. From that file:

 ---
 # How long to keep CU data?
 $wgCUDMaxAge = 3 * 30 * 24 * 3600; // 3 months

 The last attempt to change this value (without community discussion) was
 summarily shot down:

permanent (e.g., revisions aren't going anywhere for the most
 part). I guess the question is specific to the ClickTracking extension:
