Snapchat's stance on impersonation
Impersonation is when someone assumes the identity of another person to harass or defraud them. It can also include behaviours such as creating fake accounts or hijacking accounts, usually with the intent of targeting an individual.
Snapchat prohibits pretending to be someone or something you're not and attempting to deceive people about who you are. This includes impersonating your friends, celebrities, public figures, brands, or other organisations.
