In Better badware notifications for webmasters, Google mentions they may send email to generic addresses (like webmaster@ and admin@) to help alert webmasters that their site has “bad” stuff on it.
Please don’t send alerts to “generic” addresses. Those get only spam for me. It would be great to let us webmasters to set up an address for notifications.
And why in the world does Google make it difficult for people to leave a comment on their blog? You have to be a registered user of Blogger to do that. And their trackback mechanism is not intuitive. They want you to again sign into your Blogger account, who knows what happens after that. You know, I would think that Google would be aware that there are other services out on the Intertubes that aren’t affiliated with Google.
