Blackpixel...if you don't have any notifications in WMT... reconsideration probably won't do anything. Cutts says 99.9% of all manually penalized sites have notifications. If you have a algorithmic penalty, then the spam team won't touch your site (unless you are wpmu).
Our site was hit by penguin...we scrubbed our profile and did a reconsideration...and we got an automated message stating that we didn't have a manual penalty so there was nothing they could do.
On the flip side, one of our sites was hit by a virus, we got flagged...did a reconsideration request and in a week that got unpenalized after a human review. The difference was that our virus hit site explicitly stated in WMT that it had been flagged by google and that we had to do clean it up and do a reconsideration request to lose our virus flag.
