Anonymity allows people to feel uals to anonymously share information with friends and con- less constrained by the expectations of their everyday iden- tacts, without any persistent identity marker. The functions of tities [3, 25], which in turn allows more candid and honest these “tie-based” anonymity services may be notably differ- self-expressions [1, 43]. Anonymity also leads users to dis- ent than other social media services. We use semi-structured close more information [52], which may result in positive interviews to qualitatively examine motivations, practices and emotional outcomes for the person disclosing [45]. On the perceptions in two tie-based anonymity apps: Secret (now de- other hand, the lack of attribution and responsibility in anony- funct, in the US) and Mimi (in China). Among the findings, mous environments can encourage malicious behaviors such we show that: (1) while users are more comfortable in self- as trolling [33] and cyberbullying [5, 6, 34]. It is no wonder disclosure, they still have specific practices and strategies to that society in general, and HCI researchers in particular, have avoid or allow identification; (2) attempts for de-identification been fascinated with the topic of anonymity.
