The negative impacts of social media have given rise to philosophical questions around whether social media companies have the authority to regulate user-generated content on their platforms. The most popular justification for that authority is to appeal to private ownership rights. Social media companies own their platforms, and their ownership comes with various rights that ground their authority to moderate user-generated content on their platforms. However, we argue that ownership rights can be limited when their exercise results in significant harms (...) to others or the perpetration of injustices. We outline some of the substantive harms that social media platforms inflict through their practices of content moderation and some of the procedural injustices that arise through their arbitrary application of community guidelines. This provides a normative basis for calls to better regulate user-generated content on social media platforms. We conclude by considering some of the political and legal implications of our argument.

Abstract— In parallel to developing technology, demand for more energy makes us seek new energy sources. Wind and solar energy are the most popular ones owing to their abundance, ease of availability and convertibility to electric energy. This work covers realization of a hybrid renewable energy system. The scheme involves conversion of solar power and wind power into usable electrical energy using solar panel and by designing a wind turbine with appropriate calculations and specifications. Battery in this system is charged (...) by both solar and wind power, the DC output is then converted to AC using an inverter and fed to the load. The idea of water conservation through rain water collection and storage with the use of solar panel is also implemented. The main aim of the design is to create a system suitable to provide continuous power by utilization of non-conventional energy resources and making use of the additional advantage of the solar panel in the conservation of water. Power resources and load in the system are monitored and controlled in real time. (shrink)
