Hack Alerts feature - Looking for documentation on feature

I tried to search Avast website and this forum to learn more about the Hack Alerts feature recently added. Is there a description of where Avast pulls their data? I noticed Hack Alerts lists 6 instances of my email address leaked online while Have I Been Pwned lists 10. I guess I’m not understanding why Avast’s new feature doesn’t at least include the same breaches as Have I Been Pwned?

Thank you

As you already mentioned, the feature is new and there’s no FAQ article (yet).
But afaik, it’s based on Avast Hack-Check: https://www.avast.com/hackcheck

It may also be a watered down version of Avast BreachGuard.

I use Blur, to generate disposable emails which can then be disabled when the corespondant becomes a pest. Is there some way to submit a list of emails (rather than individually, one after another) for Hack Check to evaluate?

None that I know of.
