FuseClick calculates 2 categories of clicks:  All clicks and Gross clicks. "All clicks" category is clicks came from active offers as well as from error pages, in case  traffic doesn't meet the requirements. "Gross clicks" - clicks came from active offers only.
If Offer is paused and there is no secondary offer set, Fuseclicks will not allow traffic to reach the offer. These clicks will be recorded in All Clicks report. You need to tell affiliates that the offer is set as pause, and stop to post traffic.
