Therefore Kim, I think you might be proposing that MediaDefender is
possibly stepping through the IP ranges 
looking for live ports with which to further operate from as in
http://www.dailybits.com/media-defender-attacks-revision3-with-a-ddos/
and had Jans computer responded positively - then her bandwidth would
now be used without her permission to interogate other Torrent users. In
this way - mediadefender can continue interdiction activities without
being identified by ip blacklists - even though by doing so they are in
clear breach of the US wiretap Act and are in effect stealing bandwidth
from innocent users without offers of compensation.
That's suprising - I actually thought they had stopped doing that sort
of stuff.

(I just thought I would translate your (it's very useful data) comment.)
