Scott gets all the Crack-Hits because he not only posts comments but also front-page blog/news entries. Those are much more worth than a posting on the forum.
Comment on the forum is worth 5 Hits, a front-page posting is worth 20 points. I'm pretty neutral about this, but if you still find this unfair, i am sure that we could have a poll to vote on the crack-hits behaviour.
By the way, there is some really odd behaviour of this plugin when you edit your own comments. For some reason the points will be removed from your account and moved to the very first user who has registered on the site - that would be robbie. Haven't noticed any configuration settings for this one, but as soon I do, I will disable this bevaiour.
