Blogexplosion.com, is very popular these days as it increases the traffic to your blog or in their words "explode your blog's traffic".Unfortunately it violates one of Adsense Policies. I just confirmed it from Adsense Team that it is not a valid way increasing traffic.According to Adsense Team, no publisher can increase traffic to their blogs by submitting to sites like BlogExplosion.
Banned Publishers have started complaining that BlogExplosion is just a Directory.

No words have been heard from the Blog Explosion Team as yet. Google has not disabled the accounts of all adsense publishers participating in Blogexplosion. Google Adsense , according to me are disabling only those accounts whose visitors clicking the ads are referred through Blogexplosion

So, Beware , if you are an Adsense Publisher partcipating in Blogexplosion
