BLACKHAT AHEAD
Spam the shit out of
OpenSourceCMS - CMS Ratings
The place where you can test the control panel of alot of CMSs
How to do it:
Get Live HTTP headers for firefox. Log into each of these control panels, start with the one with highest ratio and go down, you might get tired.
And post someonething on the startpage, anything, javascript redirect, adsense ads + high paying keyword contnet, just alot of links, you name it.
Each time you post something, as in: log in to the control panel, post data etc, use Live HTTP Headers to save what you sent.
Now create a script in php or what you like best that posts this data that you collected with Live HTTP Headers. Set up a cron job that runs the script quite often. They refresh the CMSs every 2 hours I think.
I have not tried this but it's an idea I've had.
