I don’t see any broken images or links in those posts.
I’m not aware of any restriction you are mentioning.
I prefer to have single place for your updates on Canadian News and Media Monitoring rather than having new separate topic for each news article. These articles are getting just few replies from other members and it ends up glutting International section just with article headlines. If anyone wants to get latest from media he can visit this topic (mega-thread as you call it). There are multiple threads in OG forums now longer than 500+ posts and with timeline feature (and your browser remembering where you stopped reading) it is working very well. Good analogy is Cannabis Current Events topic.
