Not many know the real story to this, and I am not going to be the one to say it however I will give the known story behind Nyx.
Someone hacked a staff account on HF, and rep fucked quite a few people Nyx being one of them. I am pretty sure this being while Nyx was a mod of the anime section after the rep fuck occurred, and Omni notified Nyx of it being irreversible Nyx just basically turned LQ, and everyone neg repped him, and after getting to about -300 he started wanting negative reputation and trying to pull it off like he wanted it from day one.
If you want to know the real story ask someone else because I will not tell you. I am not going to be the one to leak information. I also should mention the story I say is 100% accurate information its just the whole story.
