RE: Remove profiling prohibition for frequency capping (ISSUE-236)

Walter,

Then we disagree on the merits here.  Removing frequency-capping will have fairly negative repercussions on users seeing the same ads over-and-over-and-over driving them to turn off DNT.  The group on both sides agreed to this carve-out long ago due to the perverse disincentives created in this scenario (I believe only 2 or 3 people out of ~70 ever had an issue here).  Your technical solution is simply unworkable.  Looking forward to the Call for Objections.

I am perfectly fine with frequency-capping, as long as it doesn't require profiling at an individual level. It cannot result in collection of data by a third-party if the UA is setting a DNT:1 flag. The mere fact that this particular purpose of tracking is beneficial both to the user and the advertiser does not justify in itself an override of a
DNT:1 preference. And I can think of several methods to prevent saturation of a particular user with a particular ad, for example progressively dropping least-significant bits of IP-addresses to mask out groups of users that an ad should not be shown to.

I do not recall a broad consensus about this particular permitted use.

Regards,

  Walter
