Subreddit is quarantined? What is difference in quarantined and banned?

Good day everyone, I was just trying to open r/HinduSupremacy but it gives me a pop up saying it's been quarantined. What difference in quarantined & ban as both stops you from accessing the chamber?<br><br>(Just like that stupid chamber, r/AskTeenGirls is quarantined because "it is considered to be as NSFW chamber")
