Sending the same post to 2000+ WP blogs?

I have wordpress 3.0 MS site with about 2,000 blogs atm. Most of them are posted to using some automated software I believe. Adsense doesn't seem to mind though, I just got my first check from them for $105..

Anyways I'm having a plugin developed that will allow me to make one post as the admin and have it copied to ALL of my members blogs. I was thinking CPA offers or something. Have to experiment I guess. Anyways I was wondering, do you think google's SE will punish me for seeing that much duplicate content?

I'm not ranking well at all for my keyword "free blog hosting". Yah I want *real* bloggers lol... But google is indexing the site well. site:xxx.xxx = about 16,900 results

Oh yah.. Does anyone else hate the envelope google uses to send their checks? It had no writing to speak of on it, thought it was more junk mail, almost ripped it up and thew it away! Now I gotta open all my junk mail. rarrwr!
