Hello,

What are the problems you see with the beacon being blocked when it comes
to extracting value from data?

In most instances what we look when deriving insights are ratios. For
example: "of the people that saw the red link how many clicked it". In this
scenario, with an adequate sample sizes, insights can be extracted without
any issues.

>Is it reasonable to say that ad blockers should not be blocking
EventLogging (since it's just an internal logging system)?
Addblockers prevent requests to beacons, them being used for internal stats
or otherwise (ad serving) so yes, it is pretty reasonable. A beacon does
not necessarily imply it is used for adds [1]


>If the answer to #1 is "yes", could we change the URL that EventLogging
uses so that it is no longer blacklisted by ad blockers
Any url we use it is likely to be blacklisted by blockers that use lists in
the absence of it being explicitly whitelisted. So, a naming change will
have just a short lived effect.

Another way to proceed is the opposite: whitelist the url so it is not
blocked by the blockers that -like adblocker- rely on lists. Now (since not
all blockers work with lists. Example: Privacy Badger) that is by no means
a 100% guarantee that data would not be blocked.

Thanks,

Nuria
