Negative Lead Scoring
The Eloqua Lead Scoring Model needs the ability to set negative values for profile and engagement components. For example, if someone unsubscribes in Eloqua you could set that to drop the engagement score by 50%. Or if someone indicates that they are a student you could drop their profile score by 25%.
I've observed that if you aren't careful, people who try to disengage with you (clicking unsubscribe links in emails, unsubscribing through preference forms, visiting preference center webpages) get scored HIGHER. The ability to set negative values in your model would counter this, and make the scoring model feature much more powerful and accurate at scoring leads.
P.S. I searched to see if this idea already existed, and did not find it. If it does, let me know and I'll delete this one and upvote the other!
