WARNING: HIGHLY NSFW LANGUAGE WITHIN SAID LINK, ANY REFERENCES WITHIN THIS THREAD HAVE BEEN CENSORED
The link is from a /r/circlebroke thread, expressing disgust at how much Reddit Gold has actually been rewarded to blatantly racist comments on a /r/videos thread showing a video of a black man violently punching a female shop assistant in the face then robbing a Boost Mobile store.
For those unaware, Gilding a comment is awarding the poster with a month of Reddit Gold (or the premium subscription service that the site currently operates under) which can be gifted to other users.
One comment, simplying saying "F*****g n****r" has been awarded 13 months of Reddit Gold by other users.
Several comments suggest this being the result of a 4chan /pol/ raid on reddit but no conclusive evidence has been shown as of yet.
