Advice for posting to Neighbors Feed

I see several posts from neighbors warning of random wildlife in the area (fox, bears, coyotes, etc) to warn people to be watchful and safe. I tried doing the same, since a HUGE male elk was sitting on the greenbelt in my neighborhood near the walking path. This path always has people walking their dogs and is where the neighbor kids play. Elk, especially males, can be dangerous. Ring denied my post, and I can’t figure out why. Any ideas??
