WordPress:Apa itu Blog?

Verifying Pingbacks and TrackbacksComments on blogs are often criticized as lacking authority,since anyone can post anything using any name they like:there’s no verification process to ensure that the person is who they claim to be. Trackbacks and Pingbacks both aim to provide some verification to blog commenting.

It lets you moderate comments,&you can delete unwanted comments,approve cool comments and make other decisions about the comments.
Comment Spam

Comment Spam refers to useless comments (or trackbacks,or pingbacks) to posts on a blog. These are often irrelevant to the context value of the post. They can contain one or more links to other websites or domains. Spammers use Comment Spam as a medium to get higher page rank for their domains in Google,so that they can sell those domains at a higher price sometime in future or to obtain a high ranking in search results for an existing website.
