2014-11-June-upside-down-man.jpg.jpgNothing like the illusion of anonymity to give the nastiest, angriest, most disagreeable people on the planet a voice. From slanderous, libelous and racist comments to the simply offensive and juvenile, trash trolls and link baiters create never-ending challenges for content producers.

Addressing comment spam is a frustrating and time-consuming task for organizations. Typically, companies are required to manually edit spam out of content after it has been posted or rely on moderators to filter individual posts to ensure they are legitimate, Internet security firms concur.

And every decision to delete a comment creates at least a momentarily struggle between conflicting goals. What's more important: free speech or the overwhelming desire to stomp out stupidity?

Yes, content producers have a difficult job — and it extends far beyond the challenge of finding writers who actually know how to write. Now a new report from Redwood Shores, Calif.-based Imperva reveals 80 percent of comment spam traffic is generated by 28 percent of attackers.

Get a Life

Anyone who has worked with Internet content for more than a few days ends up wondering how so many people have so little to do. Who has the time or inclination to post so many spam comments?

Sure we all have visceral reactions to certain people, places and things. But most of us have the sanity to refrain from creating multiple logons just to immortalize our fleeting hatred in the form of a poorly crafted offensive comment.

Of course, vitriolic ideation is only one reason for comment spam. Some spammers do it for economic reasons, including Search Engine Optimization (SEO). The goal is to improve a site’s ranking within a search engine result set (with respect to given search terms), which is based on the number and quality of websites that hold links to it — back links.

So posting many comments containing links to a target site increases its ranking within search engine result sets (especially with respect to keywords surrounding the link), Imperva explains.

Big and Getting Bigger

Last year, comment spam got bad enough to force Popular Science to disable comments on its posts:

It wasn't a decision we made lightly. As the news arm of a 141-year-old science and technology magazine, we are as committed to fostering lively, intellectual debate as we are to spreading the word of science far and wide. The problem is when trolls and spambots overwhelm the former, diminishing our ability to do the latter."

Yes, as I've noted before, the rules of etiquette changed the day the Internet was born. Suddenly it was OK to curse, criticize, spell words like "are" and "you" with single letters, and publish photos of wieners that no one would ever want to place on a bun.

But there is, apparently, a limit to the Wild West of wicked words and semi-pornographic photos. In recent years, US courts have increasingly clamped down on comment spammers, even if those comments are ostensibly made anonymously.
