this post reminded me of another bad consequence...less money for adsense because it throws your converstion rate WAY down...so definately don't use this if you have adsense (actually...definately don't use it for any reason... )
Just run a auto-refresh script with a counter of 0 to 1.000.000 on your site. The effects will be same. The best part is, you will be able to save $50. Cheers
These sites are main bot driven and they create artificial impressions and hits. They are against Google TOS if you are running Adsense.
What if the purpose of the traffic is not to convert sales but drive up your Alexa ranking, comScore and google analytics? Could you see it working for that? Or is Alexa immune to it?
