You have 2 sites: widget.com widgets.com You want to filter out thewidget.com from widget.com but not from widgets.com widget.com CAN have ads from thewidget.com widgets.com CANNOT have ads from thewidget.com Is it possible to do that?
By default if you block 'thewidget.com' then it is for all your sites. You cannot block any advert for any particular site(s) only AFIK. It will be nice if there is a way to do so.
