Ask HN: Any Way to Improve the Facebook HN Bot?

For those unfamiliar: https://www.facebook.com/hnbot/about

I like the HN Bot, and will sometimes check links it provides when I'm not on HN.

However, it occasionally posts links that end up becoming flagged, duped, or otherwise less desirable posts. Is there a way to improve the HN Bot so that it can pull back posts (I know fb has a delete capability), or maybe a delay before posting (avoiding these undesirables)?

Additionally, if someone has a better Idea, feel free to share it.
