Those list members may have forwarded some posts to acquaintances,
those 3rd parties may have clicked those links mostly
by accident.  I have received stuff like that quite often from
people (regardless what mail manager was) Some people are clueless
thus forward without pruning. Some careless, some time pressured,
& some 3rd parties will click Anything.

Andy C's idea is good: Track a couple of cases in apache (or other httpd) logs .
