XF 1.5 How To Set Daily Post Limit for Register User?

I am facing problem with Spam User. Few user start posting 100-200 posts within few min.
So i want to set limit for posting amount so that a user can create only 10-15 post a day. Is there any way to do this?

Does the spam cleaner not do this?
no, it doesnt.
This is the second time this user fill up my forum with Spam posts. He creates a new account and start creating threads. i think the user using any automated software for creating huge forum threads with in few min. And also this Spam user use more than 10 ip's from different cities.

i banned his two different accounts and 25 ips he used.
