Microstock Group - A meeting place for microstock photographers

I search a couple of my images using the main keywords and the images come up on the first page and they are mostly in 2nd or 3rd place. And my zymm rank is 5.  Is this good?

I also noticed with some , there is a  lot of spamming images with no relation to the keywords. Should I point this out to Keith ? Would I be burned to the stake for doing this?
