Both.
Yesterday I received the same popcon ID 2600 times, and 4700 differents ID were received
two times and 22000 ID were received exactly once.
I understand the need for totally identical systems, but then probably
it does not make sense for them to report to popcon.
A related issue is that the submission time is randomized, but if
2600 systems have identical /etc/cron.d/popularity-contest files, they
will report at the same time, causing network spikes.
