As I just wrote on
https://meta.wikimedia.org/wiki/CentralNotice/Request/Wiki_Loves_Monuments_2021

As I tried to say earlier on the Meta page, I am trying to make sure a
banner works, but decision making around banners should be done with the
international in dialogue with the local teams and the broader community.
The discussion on the mailing list and here is very very limited in
comparison to the number of people involved. This is concerning.Another
concern is that the proposal above, to implement a diet with a "cooldown"
is I think enlarging an existing problem (banner blindness) and creating a
new problem (new participants who can't find back the instructions page,
aka less uploads). Let me try to explain.
Banner blindness is influenced by for major factors:

   1. The first factor is how many different banners a person sees in a
   certain period. If someone sees 6 banners in a certain period, banner
   blindness is worse than only seeing one banner in that period.
   2. The second factor is how many times a certain banner is visible above
   the pages. If a banner is only shown five times, it is less blinding than
   when seen 50 times. If a banner disappears, a lot of users will think this
   banner is gone (but when a cyclus is in place the annoyance can be larger,
   see 4).
   3. The third factor is on how many different wikis someone is active on
   which the same banner is shown. If a diet is put in place (let's say 5x
   shown) and a user has visited above that number of pages, a banner
   disappears (or after clicking it away), that same banner will re-appear
   when that user visits another wiki. A diet does not work cross wiki.
   4. The fourth factor is how many cycles a banner is shown to a single
   user. (A cycle means that when someone got a banner a few times, after some
   time (days/weeks) a banner can be shown again for a few times.) While this
   is actually the same banner, a lot of users would experience this as a
   second/third/etc banner, or in other words, the banner blindness is higher.

(There can be also other factors in place, like banners that are shown but
are relevant for only an extremely low number of viewers, as well as banner
designs (like moving flags) that can create much annoyance, but above I
just focussed on the different ways of how the same banner can be shown.)
The third factor (in my opinion) should have been fixed already five years
ago and is a long standing problem. However I do see some progress, you can
now disable certain type of campaigns in your preferences if you do not
want to see them: Special:Preferences#mw-prefsection-centralnotice-banners
<https://meta.wikimedia.org/wiki/Special:Preferences#mw-prefsection-centralnotice-banners>
.
*Concerning the proposal to put a diet in place with repeating cycles:* At
first sight this proposal seems to be helpful to reduce banner blindness
and annoyance for banners. However, users would not get the banner once,
but four times (factor 4), which would cause 4x the annoyance, and if they
work cross wiki this would double/triple/etc the amount of banners they
experience (factor 3).
But more importantly: this diet would cause a major issue: new editors
can't find back the instructions page of the photo contest when they
re-visit Wikipedia (or the page is otherwise much harder to find back). In
other words: a lot less photos uploaded by a less diverse amount of
uploaders.
I am a huge fan of diets, but above all a banner (+diet) must by *suitable*
for the goal of the banner. In other words, the WLM banner has 2 goals: 1.
to inform people about the contest ongoing, 2. after participants have made
photos they return to Wikipedia and then the banner has as goal to enable
participants to find back the instructions page. The proposed diet is
obstructing the second goal and is damaging for the photo contest.

So if you as local organisers do not wish a bad effect because a diet is in
place, replying on the Meta page and/or here on the mailing list would be
needed.
