Is it a crime to have a fake Facebook account?
I don’t think it is. But if you do something illegal with the account, it is crime. I won’t even use a fake account. I want nothing to do with them.
Violating Terms of Service
If you’re creating a fake account on Facebook (or most other social media sites), there’s a good chance you’re violating the terms of service. In this instance, the law is clear: According to the Ninth Circuit Court of Appeals, it isn’t illegal to violate a term of service. This advice comes with some pitfalls, however, as other actions taken while violating the terms of service could still violate criminal or civil law. As always, use common sense.
