They are planning to remove the 4 post limit in 0.17:
Removing Over Posting Reward Penalties
During the July rush we experienced a massive influx of people posting as much as they could to get as many rewards as they could. In an effort to curb this “abuse” we implemented a limit on the maximum reward a post could receive if the post made more than 4 posts in the same day. In hindsight this change was reactionary and ultimately unnecessary. It has the psychological impact of discouraging engagement and adds unnecessary complexity to a system. In the spirit of KISS we feel this should be removed.

- Removing Over Posting Reward Penalties:
Translation: anyone can post as many posts as he / she wants and they may get rewards, if they are voted. Currently, you can publish as many posts as you want, but only the first 4 are eligible for rewards.
Feedback: +9, Throttling posts to 4 payable per day may have played a significant role in the somehow slow growth of the platform. If there's no incentive to write more than 4 posts, why doing it?

Amazing news! Thank you for sharing this with me Alex. How do we know when this is implemented I wonder?
It seems they plan to release it on February 7th (though this can obviously change). Once it's released, historically the hard fork takes place about a week later. You can keep tabs on its progress here:
