Propagating a campaign through word of mouth sometimes involves building volume by having many, many sources repeat basic and elementary facts - but comment spam?
"Help stop evil (url snip) word of mouth marketers like (url snip) BzzAgent.com by supporting the (url snip) Blog Publishers Association founded by legendary blogger (url snip) Jason Calacanis."
Interesting little back and forth between Jason and the others over in a comment section at gapingvoid.
Addendum: AWW CRAP. I just figured this out! If I actually tell my Movable Type blacklist to ban this particular comment spam, it will block all those URLs as well. It must be a devious plot by those "No Logo" loving lefties!
