Blogger Updates Captchas
The word verification system used by Blogger to help thwart spammers has been revised to address some problems encountered by users.
A number of users were unable to solve the captchas presented by Blogger when they tried to post to their blogs. The new system was imposed by Google when blogs hit a certain level of spamminess per Blogger's spam classifier.
Being prompted to solve the captcha doesn't necessarily mean one's blog has a problem, Jason Goldman posted:
It's important to know that if you are prompted to solve the CAPTCHA, it doesn't mean that there is anything wrong with your blog. Because of the number of variables our classifier uses, there's no easy way for us to pinpoint why your blog may have tripped the word verification (publicizing this information also serves to defeat the classifier).
Goldman also wrote that Blogger will work on a way to eliminate the captcha once a poster has been verified as legitimate. "It's important that we find ways to put reasonable barriers in place to further prevent the automated creation of spam content," he said.
Blogger's efforts to fight spam blogs will be an ongoing one. People like Mark Cuban, owner of blog search engine Icerocket, have been loudly complaining about the number of spam blogs on Blogger. Icerocket has taken the extreme step of banning blogspot.com blogs from its index.
