The only true social network is friendship. These meta-database giants are just other capital-oriented machines. Fight them. Its vitality is disguised and is nothing but mechanical. Erase all data, obfuscates all links, and blunt anyone planning to use them. There is no positive use of them. Lead them to data-poverty. Free the software and be wary about centralization.
