I wrote the details in Points broken? before I saw that you noticed a very similar problem 3 days ago.
I want the users get points for posting and replying - we may need to increase the point limit then to 10-50 (currently it is set to 5).
I agree that approving multiple posts is not what we want. On the other hand one does never know whether the first post is just a dummy post (aka "I have the same problem.") to test moderation.
Jive seems to offer also other ways to get points: "If you are moderating new user content based upon points, be aware that the Korean Spammers know the Jive platform very well and will being earning points outside of discussions. For example they will search, like/rate content, and post personal blogs (not moderated by points). Also if you give points for tags, they still get the points even if the content hit the moderation queue." (source https://community.jivesoftware.com/docs/DOC-156727)
