	Thats true, but can they avoid it?  I'm considering writing a
database pollution bot, which runs around, claiming to be Mozilla or
IE, and randomly following a link once per minute.  Why?  Database
pollution.  If there are a few thousand of these randomly collecing
links and creating arbitrary (or perhaps biased) viewing habbits in
the databases of the advertisers, then their individual data becomes
worth less.  They'll need to actively solicit peoples permission to
collect data before doing so, to avoid people polluting their
databases.

	Similarly, putting a randomly generated email address in those
sign up fields produces pollution in the data used by spammers, which
costs them (and no one else) money.  If you run your own site, you can
even bit bucket the email, trading their bandwidth for yours, and
making them think they're delivering more junk email than they are.
