One possibility would be to check for the presence of a cookie on the user's computer. If we don't find it, they get a message...

Would that actually prevent anything? First of all you "punish" people who disable cookies in their browser (and I know quite a lot of people who do). Secondly, I don't know much about these harvester software packages, but even a simple Perl bot could use HTTP::Cookies so I assume these programs can too :(
