All content decisions are controlled by the community. All data entries are always pushed into the blockchain but what happens if someone decides to spam the network. This is possible and probably will happen but this is where the community of miners decides what content they want to show. The overall content always remains immutable in the blockchain but some may not follow our basic mining rules.
As a community we will have to deal with spam and inappropriate content. Content shown as public or private is controlled by the owner of each node. All decisions are made by the community which is the benefit of a decentralized blockchain system. There are no rules or regulations that stop anyone from displaying all content and this is the key feature and benefit of decentralized applications. If you would like to become a partner/miner and contribute to this project feel free to contact us so we can allow you to add a miner node.
