I disagree.

Initially, the image used in that popup actually comes
from a different server, but that's trivial.  What I
see as a bigger issue is that blocking the image from
the server leaves the user with an empty div block
covering the page, and blocking the site serving the
div content could essentially render the div
'uncloseable'.  Of course, this is more along the
lines of browseability, and does not seem to have any
very obvious security implications above and beyond
what can be served via a page without the annoying

Notice that it looks like an IE window even in

this type of ad

seems to be 
thoughtful enough to only display the ad the first

Tricky little devils aren't they (and getting
trickier all the time).
