Why I have closed the comments for non registered users

I was sick of comment spammers who used to comment using softwares. So, I have closed the comment section for non registered users as of now. We are planning to make the website dofollow blog means the comments will be dofollow ,but only for registered users. So,if you have any problem regarding anything,do register here and share with us.

Some of the spam comments I am getting here at computer talks:
