Running a URL shortening website

I have a website that allows users to shorten their links. They can shorten the URL of any website, which could be, for instance, a phishing attack page (page to steal users' credentials) or a pornographic website for that matter. For clarification, the short links generated in my website redirect to users' original links. Could the entirety of this service be haram because of those minority of malicious user-generated links? P.S. it's a renowned service, and widely used for many purposes like marketing to track campaigns...
