I'm not 100% sure how it works, but I think the mods are very trigger happy when it comes to deleting content that they don't judge to be appropriate. This has a positive effect on maintaining the quality of the overall posts, but is a negative when one person's opinion shuts down a potentially interesting topic.

I think you erred by trying to make two posts about the same thing in one day that. That might be something that gets you flagged.
