No, it works by how much you post, if you go around spamming "thanks" or "nice" you won't get anything, but if you make nice long well-written posts (not spam) you'll get plenty of points. Well spam works, but if you start copy & pasting guides for post or just typing garvage for points, someone will notice and don't be surprised if you get our points taken away.
Also note, if your post gets deleted, for whatever reason, you'll lose those points you got from that post.
