How about a +/- button per user per post. So for each post each user views they see a + and - button, they get one chance to click one of the buttons, once clicked the buttons disappear for that user for that post.
+ means the post is positive/contributing
- means the post is negative/detracting from the topic
At a certain -ve threshold the post is shown collapsed - i.e. just a single line with poster and date/time. If you want to view the post you can expand it.
