I have often asked members of this forum to lead me to some dofollow blogs to post comments and help in my link building. I now regret it. I had to clear my blog with 20000 nonsensical comments which were posted on my blog by 'link searchers'. For all those who use these methods, posting a valid comment will help you gain more links. You don't want to be blog spammed, so why spam others. I hope this does not sound too 'preachy' and is of help to you guys. Thanks a lot for all your help.
