What is the explanation for this? My spam folder is
full of emails from
wiki mailing lists too.
Perhaps many users don't know how to unsubscribe and mark them as spam and
Google filter has learn it?
Since it includes a List-Unsubscribe header, when reporting it as spam,
Google prompts the user with something along the lines of "Do you wish to
unsubscribe rather than report as spam?"
