Spam and Eggs

I havent forgotten this blog - how could I? I get between 5-7 spam messages a day for it....!!
And can anybody explain exactly how "Thanks for sharing this link, but unfortunately it seems to be offline... " is effective spam? Do they search for blogs and forums that post it? Do I need to scrub stuff like that off the blog?

There will be doing some southern historical stuff at the Universalist Convocations at
Newberry SC this upcoming May 2011. So it's not like I'm ignoring history completely.
