Social networks (SNs) are social structure built of individuals and organizations linked by ties which allow them to interact. The conception, planning and building of SNs require from developers detailing basic elements and main functionalities based on the design and architecture of SNs properties for centralized and decentralized types. The development of a SN allied to privacy aspects are, however, a hard work since there is no general agreement about how privacy should be integrated into a SN. In order to guide developers in the early development stage, in this paper we propose groups of properties that collaboratively work to align design choice options and distinguish best practices toward privacy-friendly SNs. As a result, we provide recommendations as well as a binary worktable containing positive and negative impacts of collaborative group of privacy-related properties which might be used to reduce developers efforts.
