Facebook share - posts not appear at recent posts

I've got some messy thing with Facebook "Share this" module. Some time ago Share button stopped working properly. When someone clicks Share this, link with content appear at his wall, but people can't see this action in recent posts, they need to open his/her wall to see this. What happened with Facebook? Anyo开发者_如何学JAVAne know?

It is probably determined to be low quality by Facebook algorithms and thus not showing in the recent feed. If this is published via an application, check the insights on your application.
