I think the photo sharing on Facebook it unsecure as it should. for example, we publish the photos teased friends our in Facebook. Post time we could not think of anything, because in facebook of I have but same friend . but, when our friends share the photos our. Shows that the picture of us within our group anymore. connect with the case that we can see post Our friends have come to share we , we can't know that content in there is truth or false?
