This chapter explores citizens’ use of social media during the Covid-19 pandemic in Tanzania against the backdrop of the restrictive Cybercrimes Act 2015. Guided by Uses and Gratifications Theory and through Grounded Theory as a method of inquiry for data collection and data analysis, the study found that, of the 60 citizens interviewed, 75 per cent supported the Cybercrimes Act 2015 as a relevant law but acknowledged that the same Act limits the construction and dissemination of their Covid-19 messages. Only 18.4 per cent of respondents trusted information posted by ordinary citizens while 81.6 per cent trusted information from verifiable sources. Data analysis further reveals a weak citizen journalism practice occasioned mainly by six factors: limited freedom of expression, poor knowledge of Cybercrimes Law, citizen journalism values underutilisation, poor social media literacy skills, and limited message construction and dissemination. Nonetheless, respondents revealed that social media remained the most popular platform on which citizens discuss Covid-19 preventive measures amidst reduced social interactions. Equipping citizens with social media literacy skills was found to be important to reduce misinformation and disinformation. The chapter calls for a review of Section 20 of the Cybercrimes Act 2015 to enable citizens, especially during pandemics, to seek and impart information more effectively, devoid of fear of repercussions.
