Limit to how many blog posts can be posted

Is there a limit to how many posts a user can make in a day? Yesterday the impersonation feature was used to create posts on behalf of a user and they got the following error message:

"Your posting frequency has exceeded allowed rates. Please wait 10 minutes to post again".

This issue is still persisting today, is there a way to clear it? Is there a way to remove this limit? I didn't see it in the blog admin panel.
