Go into the admincp> Settings>options> scroll down to User reputation options>

Then under minimum post count change it to whatever you want. NOTE* they will still be able to send rep but it will show as a grey box..this means the rep does not count and has no effect.

If you want disable users with a certain amount of rep from even being able to use the rep system then, you need to create a new user group, set the post count to be in that user group to your liking, then go to

Admincp>Usergroup>usergroup manager select the group you made>hit go>scroll down to use reputation permissions> and tick>can use reputation to no.

This way only users in the usergroup you created will be able to use the rep system. So basically make a new usergroup and edit it. allowing only members with your post count requirment to access the rep system.
