Came across some posts that were deleted and the reason said "Reason: np vore"

Example: rule34.xxx/index.php?page=post&s=view&id=9207855 (this one's a shame it got deleted...)

Can anyone explain to me what is "np vore"?

np = Not Porn

If I had to guess, they thought it wasn't sexual enough to stay on the site.

That's just a murder...

Considering that the gif ( aryion.com/g4/data/965660...Delt-965660-Lapis+1-3.gif ) has Lapis digesting Pearl and her butt and hips growing as a result
and it has two follow-ups showcasing Lapis' post-vore bubble butt:
rule34.xxx/index.php?page=post&s=view&id=9207872
rule34.xxx/index.php?page=post&s=view&id=9207890
whoever thought the first part was "not porn" must be insane, like wat ._.
