I wonder why my tutorials are almost always denied post boosting

I really don't understand. It would be easier if the person responsible for curating Ecency's system gave some feedback, said where you went wrong and where you went right. In the past they even gave me two or three feedbacks, but now it seems not anymore. Of course, I'm not criticizing the system negatively, but it's a little bad to have your boost denied without knowing why it was denied so we can correct it in future posts...
