You have exceeded the allowable number of posts without solving a captcha.

Blogger.com has a limitation on the number of posts that you can create in a single day with email without "Solving a Captcha".

When the limitation is crossed, if you want to create more post by email you will get your mail back with the error message "You have exceeded the allowable number of posts without solving a captcha."

What should I do?

If you crossed the limitations, you have to wait for 24 hours. After 24 hours, the word verification will automatically be removed.

You can create a new author of your blog and then create a new email id .
