Alternative ad feeds, for non offending, or local feeds.
Service for google ads and the likes, to make people
comfortable with the ads they send you.
A free service for the users - you choose "Ad Groups" -
filtered groups of advertisements. So YOU decide what
want to see.
You can see in advance a list and short
description of the ads and where they are from.
Or for a small pay, make your own group. If you make
own, you must at least once before the day that
who is signed on to your group browses, enter and
the ads. A group must have at least 10 paid ads in it.
is halfbakery, so I didn't think of all the possibilities. But
you get the idea.
If you didn't update your group, the browsing people will
see the default ads they see today.
Perhaps a TargetedWebAds.com site to interface with all
the large advertising feeds in the various countries. It
seems there aren't too many for each country, maybe
100 sources of online advertisements (banners and so).
