Looks like the "Guardians of Peace" scored another victory ... Sony quietly gave in to another hacker demand by wiping almost all traces of "The Interview" from its social media pages.

Hackers threatened top level Sony execs Friday saying, "We want everything related to the movie, including its trailers, as well as its full version down from any website hosting them immediately."

The movie studio almost immediately obliged ... the movie's Twitter page no longer has any tweets, the Facebook page has been deleted and all "Interview" footage has been wiped from its YouTube page.

Sad.

1:50 PM PST -- The hackers also released a message Saturday afternoon mocking the FBI ... saying, "The result of investigation by FBI is so excellent that you might have seen what we were doing with your own eyes. We congratulate you success. FBI is the BEST in the world."
