Lost Camera Possible Blackhat way to find it?

I lost/had stolen an expensive camera a little over a week ago. I registered on cameratrace which basically searches different picture databases scanning for the Nikon's serial number in the exif information. Nothing came up so far, not even pictures I have posted on the internet or my personal blog. So I was curious does anyone know how to search for exif data, specifically the camera serial number, through say wordpress blogs or other websites besides Flickr, Picasa, etc.?

Looks like this in quotes, "Serial Number : 3223350"

I have scrapebox if anyone knows a footprint I could try to run. Any ideas would be appreciated.

It's sad but it's gone for good, get over it because you're not getting it back.

Check Craiglist...

It was on a small island in Greece. But to say give up it's gone is not the BHW way. There seem to to be some success stories from cameratrace and a couple other similar websites. Any chance is good enough for me.

Claim it on insurance.
