As we have a lot of students I get quite a few notifications about breaches. Sadly I get notifications about accounts that do not exist within the organisation for already over 10 years. Yet the account details keep showing up at new breaches that seems to be selling extreme old details.

I can totally understand that you do not want to remove the count of the amount of breaches found. But it would be nice to be able to mute new findings for accounts that no longer exist. That saves us going thru long lists of accounts every breach. While the majority of the lists hold mainly accounts gone for for ages.
