A far better approach is to use software that blocks *all* cookies, and
then have an exemption list for those sites that *YOU* visit that specifically
need cookies in order to function.

Remember - cookies as data harvesting tools only work because a large
percentage of people allow cookies. If the *default* behavior of people
was to tolerate only cookies that allow (for instance) session management
of a single visit, or only retain very basic cross-session information,
then the site operators wouldn't have much reason to use cookies.

Something that's a *bigger* issue is probably the infamous "web bug", which
usually shows up as a 1x1 transparent pixel. Now *THERE* is a area where
a "black list" might be more useful (because you can have an <IMG> tag
that points off-site to a tracking service, where the user may have
said "only allow cookies from this server").

There's Unix software for all this at www.junkbuster.com. I have *NOT*
tried their Windows software. It's not a *total* solution, but it's
a start.
