A comment spam is generally characterized with links and no sense, understandably so since its main concern is to be able to take advantage of the algorithm techniques of most search engines in making certain websites rank higher than the others.

Senseless as a comment spam may look at the outset, the makers of these said comment spam are extremely intelligent creatures that are properly harnessing the power of the Internet and its users to generate undeserved income.

Strangely enough, the object of affection of the makers behind every comment spam is not to gain popularity from the people and websites that they are spamming, but rather they use it to get an edge in the totem pole of user access which we know to be called search engines.

Comment spam in huge volumes actually allows the culprits to generate high ranking in search engines such as Google, Yahoo and Ask Jeeves. It helps them generate more revenue from receiving more clicks and having their links displayed all over the World Wide Web for all the people to see, regardless if these people care about what they're advertising or not.

The allure of resorting to generation of a battalion of comment spam actually emanates from the fact that it works. No matter how hated spammers get for being an online pest for websites, they get to earn a lot from it. Even when the growing number of efforts to reduce comment spam is alive and kicking, a lot of people are doing it since it is a very powerful marketing ploy.

While thoroughly extinguishing comment spam may seem to be an impossible feat, there have been various ways created to diminish, if not eliminate the influx of comment spam in various online systems. One way of eliminating comment spam involves completely blocking off all comments. However, this method is very self-limiting and deprives the user the freedom for healthy online interaction. Not all comments are comment spam, and anyone who deprives himself of getting authentic feedbacks for the sake of blocking a spam comment is at a losing edge.

Some companies have already launched their own versions of anti-spam techniques for the benefit and protection of their users. Still, even with the best of the best anti-spam method, a comment spam can still find its way even in the most protected pages. But it is better to have some level of protection than none, so every user must exercise his or her right to have spam-free interactions by selectively seeking the websites which are more protected and encouraging other websites which are not entirely comment spam-protected.

Filters are also used by most systems to purge comment spam, but they need to be updated frequently since these notorious comment spam authors are extremely resourceful people with a knack for taking advantage of every online loophole they could find.
