Blogger's official corporate blog mentioned the "spamalanche" that has search engines, blog search engines and net advertisers in a tizzy. http://buzz.blogger.com/
They are now working together to eliminate the economic incentive for splogs by identifying them at their source - by domain - and not indexing them.
Can CAPTCHA Stop The Spamalanche?
The "CAPTCHA" test is a method by which automated programs that post or create blogs can be foiled--where the user is asked to type in a sequence of letters from a line that people can read, but computers can't decipher.
Blogger is currently working on ways to reduce false positives and ensure that once a blog with word verification has been established as legitimate, the blogger will no longer need to solve the CAPTCHA.
Why Create Splogs In The First Place?
Splogs generally fall into one of two categories, notes Mediapost: Link farms, which pack hundreds or even thousands of blogs with gibberish or recycled content, and contain multiple links to a particular Web site, which allow them to game Google's PageRank algorithm, creating artificially high organic search rankings; and spam blogs that simply recycle content with AdSense or other advertising on them in the hopes of making money from errant users clicking on the ads.
