Ex-Porn Star Sasha Grey -- 'CIA' Ex-BF Ordered to Stand Down

First, Sasha Grey walked away from pornography, and now she's doing the same with the abusive ex-boyfriend she claims lured her into porn in the first place -- he's been ordered to stay away from her ... or go to jail.

TMZ broke the story ... Grey filed court docs seeking protection from Ian Cinnamon -- an ex-lover who told her he was a CIA spy. She claims he subjected her to years of abuse and sexual assaults.

Sasha got a temporary restraining order last month when he started sending her threatening messages.
