Trackbacks and Pingbacks?

I always get trackback/pingbacks comments from other people posting my stuff on their site.

Now I do not approve these comments....why do i see other blogs doing this? What is the benefit?

 

I believe you keep getting /backs from autoblogs. No much benefit from this.

 

Enable akismet plugin it will reduce spam comments. You can mark such sites as spam so they will no longer disturb you.
