Reason As you may already know, r/ethtrader has a topic limit tool https://donut-dashboard.com/#/topiclimits which is in constant evolution and some pros and cons appear during the fluctuations of real world news and the community activity.
In this case, due to the lack of amount of posts because of a decrease in r/ethtrader activity combined with some specific content getting traction, some topics get stuck on the front page for too long making impossible to other new content about an specific topic for being published, making new fresh content that falls in the same category but talks about other "topic" to get delayed or forever forgotten.
Solution Mark posts older than 48 hours as ineligible for topic limit. This solution is the simplest approach and prevents for overengineering with another solution involving dynamically calculating how many posts are being shared, etc.
PRO Fresh news wont be delayed or forgotten for having multiple posts about the same Limit topic on the top page filling the spots available and being "old" news.
CON Duplicated content could increase but mods can always remove already shared content.
