[Plugin: WP-Click-Tracker] Crawlers Registering as Clicks

I’m using the WP-click tracker to track ad and link clicks on my site, but I am getting almost 10 false clicks per link per week from crawlers. I was wondering if there is an easier way to filter crawlers than inputting each of their IP addresses in the ignore slot.
