How can I apply per day blog publishing limit for the user roles?

Pro version of the BuddyPress Member Blog plugin provides a feature to apply role-wise blog publishing limit.
It has the following features:

• Per Hour Restriction: Using this option you can apply per hour blog posting restriction to the selected user role. It means He could not be able to post the blog more than the specified limit in an hour.
• Per Day Restriction: Using this setting you can apply per day restriction to the selected user role. It means He could not be able to post the blog more than the specified limit in a day. This limit should always be greater than per hour limit. For example, If you have set 2 blogs posting in an hour then the per day limit will always be greater than 2.
• Per Week Restriction: Using this setting you can apply per week restriction to the selected user role. It means He could not be able to post the blog more than the specified limit in a week.
• Per Month Restriction: Using this setting you can apply per month restriction to the selected user role. It means He could not be able to post the blog more than the specified limit in a month.
• Per Year Restriction: This setting allows you to apply per year restriction to the selected user role. It means He could not be able to post the blog more than the specified limit in a year

if the user will try to post the blog more than the limit specified, He will get a popup box stating that his limit is exceeded.
