Reddit also has some absolutely fascist mods. For example, it's well-known that if you post anything that is against illegal immigration (and it gets too many upvotes!) /r/worldnews mods will go through and ban you after the thread dies down.
I was once banned there 48h after a polite discussion on the economic costs (citing various sources) for "hate speech". I got too many upvotes so it was noticed. Appealing to a mod resulted in him "examining my posts on other subs, and given who you voted for the ban will be permanent".
Actual hate speech is one thing, but far-left mods of major subs are using the banner of hate speech to silence well-informed opposing views.
