Hello Blackhaters, This is the second request here, I got some quality of responses to my first post. So thank you all!. I am currently working on my new site, which started a month ago. Trying to push my ranking through blog commenting. Please suggest me some quality and the best RSS and Ping tool to my links crawled by Google. My backlinks are not getting crawled since a long. I used pingfarm and masspinger, but would like more tools that you prefer.
