I have a Comcast email account that was hacked years ago. They even got my password from Comcast. (I have been given Comcast $200 monthly, and just figured they had decent security?) I now have 2FA from Comcast, but I get hacking emails daily. I don't care about the emails. They keep me up to date on the latest scam. This email is not attached to anything important besides my doctor. Is there something a Russian hacker could do with my email address? I said Russian because they told me they were Russian. 15 years ago I responded to a friendship ad on CL, and that's how I got on the sucker list.
