 The ethical concern about SNS constraints on user autonomy is also voiced by Bakardjieva and Gaden (2012) who note that whether they wish their identities to be formed and used in this manner or not, the online selves of SNS users are constituted by the categories established by SNS developers, and ranked and evaluated according to the currency which primarily drives the narrow “moral economy” of SNS communities: popularity (2012, 410). They note, however, that users are not rendered wholly powerless by this schema; users retain, and many exercise, “the liberty to make informed choices and negotiate the terms of their self-constitution and interaction with others,” (2012, 411) whether by employing means to resist the “commercial imperatives” of SNS sites (ibid.) or by deliberately restricting the scope and extent of their personal SNS practices.
