First it started when /u/Pazians posted this thread in /r/drama saying the mods are being too harsh and banning without reason.

I gave him advice and said they're really strict and he should just make an alt if he wants to discuss the show and amusingly enough they responded by proving my argument and banning me for this. I rarely went there to begin with.

Long story short, the GOT mods are clearly Lannisters and probably have sex with their siblings, spread the word
