Spam Barriers
October 18th, 2005 | Published in Google Blogger Buzz
One of the ideas I mentioned yesterday was making it more difficult for would-be spammers to post. Earlier today we pushed out a change that will prompt some users to solve a CAPTCHA if our spam classifier identifies the blog as spammy.
We plan to quickly iterate on this approach a bit (as well as extend it to posts created via the API). So far, we have observed a slight decrease in the amount spam being created. There's clearly more to do.
Update: Some users are having trouble solving the new CAPTCHAs and are seeing CAPTCHAs when they shouldn't be. We'll be pushing out a fix for that shortly.
Update: This should now be resolved.
