YouTube'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.
In cases where YouTube determines that an account was established to impersonate another channel or individual, the account will be removed. Impersonation can happen on YouTube in two ways: impersonation of a channel or an individual.
