Does anyone use Volusion's ROI Tracking?

I've been using it for many years. For the most part it seems to work fairly well.

However, I've never really understood why it records clicks for campaigns that I have not used in upwards of 10 years. Links that lead to non-existent pages, yet are still recorded as Clicks.
I get it that people save links, and that search engines can keep stuff around a long time, but to see literally hundreds of clicks (in the last 30 days) for links that are 10+ years old and not used since- that does not seem like reality to me.

I submitted a ticket, but the reply I got back said only that the link must still be getting used somewhere.

These links never show Sales, just record clicks.

Any thoughts on this?
