Leslie Jones -- freshly back on social media after getting hacked -- just posted something that has revenge written all over it.

Leslie who was targeted by racists and hackers recently, went radio silent, but now she's back, posting a pic of the comic book, "100 Bullets," with a caption suggesting she's down with the plot.

As for that plot ... it's about a secret agent who give a briefcase to someone who has been wronged. The briefcase contains a gun and 100 bullets which cannot be traced, and the idea is for the victim to go after those who done him or her dirty.
