This is a wide spread phenomenon on the platform. Sometimes its just a few comments or even dozens of comments in response to an original comment on a post being grouped together in another button saying (x number of replies) but when you open those replies its either nothing, or significantly less replies than the prompt described. Its mostly all on posts that are political in nature relating to the current fascist takeover in the USA, Luigi Magnione, amazon union busting, anti laborer’s rights legislation, loosening of child labor laws and other topics related to the wider topics regarding disappearing human rights under emboldening fascist authoritarianism. many of us have seen the news articles that mention allegations of reddit censoring comments and giving people violations for liking certain content but nothing is being said about the actual extent of this censorship. But when you can see hundreds of comments being deleted from a post such as this one here, it doesn't bode well for the future
