I have a common name Gmail account. The password is rather complex and I would be surprised if it leaks as only I and Google know it. However, I would get reports that it’s on the dark web with blanked out password values. So I never knew if they actually compromised or just something else.
They would also report when some random site that used my Gmail address as user id was on the darknet that I don’t care about. I don’t care if my fidofido account is leaked. I never use it and if I did, then I would reset.
I think if the data were useful Google would have kept this up.
I bet they keep tracking though, just keep the reports internal.
