Is your post not visible to anyone in the community except you? Aren’t you getting views and likes on posting in communities? If yes, then reason is you are sharing same content to several communities or links from a particular website, resulting in marking you as spam by G+ filters.
Don’t worry this not any kind of ban or restriction. But it is a sign that you are violating G+ policies.
How to get Google+ status visible in communities?
