Is not it a Keyword Spamming?? Oes Tsetnoc, Ose Tsetnoc Official, Wallpapers by Oes Tsetnoc, Oes Tsetnoc and Oes Tsetnoc

Recently there was a SEO Contest "Oes Tsetnoc" and I made this blog to test.. And few days back I changed it title and description and Add some targeted keywords.. It has many keywords (oes stetnoc) on it's main page.

Earlier it has only 4 or 5 targeted keywords and was ranking on 4rth page. Adding more keywords, I was thinking Google will penalize the blog. But Google didn't.. but changing the title and getting more links it moved to 2nd page..
