Hard to say.

I suggest you wait <wink>.  I saw a lot of these last week, but a lot less
this week so far.  As advertising, sending a single URL has got to suck:
who would click on it, and why, especially after the novelty wears off?  For
reasons explained earlier, if this is combined with the minimal-header
gimmick, positive tokens generated for the absence of assorted header lines
will eventually get high spamprobs too.
