(CNN) The timestamp on Leslie Jones' most recent -- and possibly last -- tweet was just past 10 p.m. She had reached her limit.

Jones had just spent 12 hours on Monday calling out her harassers on Twitter -- sometimes she'd reply, other times she'd take screenshots of their hate-filled comments and share them with her followers. The "Ghostbusters" star was fighting back.
