This study identifies the key thematic content of these Tweets and then conducts an in-depth critical analysis. These questions will be addressed in the research: “What are the principle discourse typologies and their intertextual interpretation of hashtag activism #DeleteFacebook?”, “What were the key themes that emerged during the #DeleteFacebook hashtag movement?” and “How can we interpret the online engagement with #DeleteFacebook as hashtag activism?”.
