One of the biggest, though, is the "shadowban". Used to silence critics of reddit, people with different political opinions and even people just promoting their own things. That last one is surprisingly important, because it basically meant that few content creators could ever hope to gain popularity.
I think the aspect regarding content creators is one of the largest differences between Hubski culture and reddit culture. I would encourage you or anyone else reading this to check out this post from mk:
People in general today have this nasty habit of equating "not participating with" or "disagreeing with" to "censoring" or "banning." A few miles away from me is a Diesel shop where the owner got on the news when he said he would refuse to serve openly gay customers and give people discounts for bringing guns into his store. This, naturally, resulted in quite a backlash from the local public, generating protests and comments expressing disagreement online, particularly in the news website's comment section for the story. One of the most common complaints from those who took the shop owner's side of things was that he was being "censored" and those who disagreed were being "intolerant" of his Christian beliefs. It seems that people have to constantly be reminded that freedom of speech doesn't obligate everybody to agree with and support what you have to say, and that it also allows them to speak openly in disagreement with you. When A&E cancelled Duck Dynasty, many were accusing the network of "censoring" the Robertsons, as if A&E doesn't own their own network and doesn't have the freedom to choose which programming it airs based on their own internal standards. It's getting absolutely ridiculous.
Isn't that the very definition of censorship? You might agree with it but it's still censorship. I found this definition of censoring in the merrian webseter dictionary. I think it's pretty clear.Censoring: to examine in order to suppress or delete anything considered objectionable <censor the news>; also :to suppress or delete as objectionable <censor out indecent passages>
