My password is on the list (afforess@gmail.com). I used a unique password for my Google account that I have never ever used for anything else. So I don't see how this leak could be anything but a leak from Google's servers.
I have 2FA and its been enabled for years. So I guess I am safe.
one of mine was too, however the password was an old one from quit a long time ago.
Mine is on there but the password is a simple one I use on sites I don't care about and never used it for my gmail account. Can only assume it's been scraped from another site.
