CAPTCHA Verification Required For Excessive Posting Volume

Occasionally in Blogger Help Forum: Something Is Broken, we see a query from a confused blog owner.

I made a large number of posts today, and Blogger is now requiring me to solve a CAPTCHA, for every post. I tried to find the form to submit, so that my website could be reviewed, but I could not find it. What do I do, now?

This blog owner, like too many, does not understand the spam mitigation policy.

Long ago, we first became aware of the Blogger policy on excessive posting volume. At the time when the anti spam policy was first publicised, we were told that CAPTCHA screening would be required, for any new posts exceeding a count of 50 in any day - and that the counter would reset at the end of the day.

Recently, we have some blog owners explicitly state that they are publishing less than 50 posts, and still being subjected to CAPTCHA screening. There are two possibilities, here.

• The Blogger anti-spam policy is dynamic, and the threshold may vary, dynamically, depending upon details not being stated.
• The breaking time of the day may not coincide with the local clock observed by any blog owner. It's possible that some activity from the previous local day might contribute to a count of 50 posts, as observed by any given blog owner.

It may not be accurate, to advise any blog owner, reporting this problem, that exactly 50 posts, in any day, will consistently trigger CAPTCHA screening.

In complete accuracy, we can only note that excessive posting volume, approximating 50 new posts in any 24 hour period, will trigger CAPTCHA screening - and that sometime during the next 24 hours, the count would reset - and normal posting would then resume.

It's possible that the "24 hour" period is calculated according to a local clock - but the reset, following a period of acceptable activity, is a worldwide process for all blogs, simultaneously. This would make the reset period more like "48 hours", for some blog owners.

The exact time span of the "48 hour" period is not known. This is simply a reality of the 24 hour, worldwide, use of Blogger.

Other cases where high posting volume may be a problem include use of Mail-To-Blogger, and the Blogger app on smart phones. Mail-to-Blogger now produces Draft posts, which can be published from the Posts menu. We have reports that the Blogger app is also saving Draft posts - but we're not yet sure what options are provided for Publishing the Draft posts.
