How do I report a sub and mod for allowing and encouraging hate speech?? I've already reported the user for hate speech, however, I would like to report the mods and whole sub as it is an ongoing issue. I also just discovered that the user I reported has also gone "real life" a couple hours ago and is currently harrassing me on other social media platforms despite there being no link between mi Reddit and other socials that I can find. Sub mods are refusing to intervene. Please give step by step instructions if possible. Thank you
