If people want the topic to be more diverse, then post things that you like. This thread is not being overrun by vore pictures, and this could easily be balanced for anyone who doesn't like vore by just posting things that you like too. By doing this, the topic isn't just vore and can be more varied in content.
In my opinion it would feel too competitive due to the resolution and amount of the images, if that makes sense? I think the biggest reason why the vore comics felt obtrusive is because they were posted in large resolutions, even on my 75% zoomed out browser.
At least these are my reasonings on why I didn't post anything special interest-related and just closed the topic when the vore comics were being posted. The rate at they were being posted, and the amount of actual web-page they took up, really made it too much of a hassle to begin discussion for me.
