When I think of identity theft , I imagine the perpetrator as an unknown, faceless shadow. I'd never expect an identity thief to be living under the same roof as me, especially a family member. This is precisely what happened to u/onlytwinsthrowaway , whose evil twin sister used her name to start an OnlyFans account. OP found out through a mutual friend, who sent a link to the account and asking if it was her. What a nightmare.
