I tried seraching for an answer to this question, maybe I am using the wrong keywords.
We use a horizontal banner ad at the top of the forums. Some advertisers have complained about the Ubbthreads feature that takes a user directly to the latest post (auto-scroll), obscuring the top banner ad, yet the ad tracking software counts it as a page view.
Quite simply, this is how the post system works, when a user who's logged in clicks on an unread thread, it jumps to the first unread post; if a user who *is not* logged in clicks on it, it starts at post #1.
