why didn't Comcast stop sending these messages after the customer contacted them to tell them he had seen and received their message? Personally, I'd guess it's because (like far too many parts of the internet) their implementation is subtly broken, and not because of anything nefarious. I don't recall the details of how it worked when I was the recipient, but I think the message correctly went away after I acknowledged it. I'm OK with treating repeated notification as a serious bug, just against equating a failed attempt at customer notification with a man-in-the-middle attack. I'm not universally against flooding Comcast executives and board members with feedback, but I'd prefer to reserve it for the cases where their intent, rather than their buggy implementation, is the issue.
