Why are my affiliate clicks so high?

I signed up to be an affiliate of wpmudev and copied the banner ads onto my pages. Everything looks great, but...

I only finished publishing the posts this week and haven't had any hits on the pages yet (a problem with my robots file, but that's a different story).

When I look at my WPMUDEV profile and look at my affiliate stats it says I've had over 3,000 clicks. How is this even possible?

Sorry if the is a SNQ (stupid newbie question) but I'm loving my WPMUDEV products and want to use everything to the max.

Thanks.
