Shirky spam?

Over the last few days I received multiple e-mails about a message submitted using an e-mail address I use only on my weblog and it’s feeds. The interesting thing is it appears this e-mail address was used to send a message to Clay Skirky‘s NEC list. It looks like a spammer might be crawling weblogs specifically to spam weblog mailing lists and it’s the first time I have observed such a thing. Watch your inbox for a message from “” for approval of a message subject of “Re:” and you might observe part of a trend.
