Here is a hort report on this experiment...
I started a week ago by searching OSM France tile server logs for
referer and checked manually if the map on the refering page was
correctly attributed.
This allowed me to create a short list of 20 entries of sites using the
french styled tiles and the humanitarian tiles (yes, it is made by OSM
France).
I then modified our nginx based proxy_cache configuration, to redirect
some tiles to an "attribution tile" only for the domain in the list.
For two of them, I tweeted about it... the most visible one is the
moroco yellow page service, generating a little less than a million
daily tile requests on our servers.

In less than 24 hours, the attribution appeared and I removed them from
the list.

Then I included an email address in the attribution reminder tile... and
got emails back within a few hours.
Some were asking how to do the attribution, others telling me the
attribution was now ok and asking how to remove the reminder tiles.
In my answers, I also remind that our tile service made by volunteers on
donated hardware is not unlimited and inviting them to have a look at
switch2osm to setup their own tile server or use a commercial provider.
Up to now, nobody complained :)
Yesterday, I've started automating attribution checking using selenium.
For each referer, a python script loads the page, searches for tiles,
then looks for attribution text or link. The result is stored in a
postgresql database which allows to group referers by url, hostname and ip.
The attribution percentage I currently see is around 70-80% which is not
that bad.
My next major step is to use the same technique to remind about tile
usage policy...
To do something similar on osm.org, a first step is to extract referers
from the cache logs, then use the automated attribution check to
evaluate the situation.

That would be a good option for those that use third party providers
of OSM. But to be honest, from my experience I highly doubt that even
corporate members of OSMF, like Mapbox would do it, when their client
Facebook (also corporate member of OSMF) after one year and half,
still has maps with lack of attribution or attributed to HERE, when
it's clearly OSM.

I am sure others may have seen this 'blacklist' implementation for
showing a reminder about attribution.

Worthy of consideration for openstreetmap.org
