It’s simple really. Reddit is shit at making memes, and as such they steal memes from here and other places and then they make the memes normified, and at the same time Reddit bitches about shit like Instagram stealing their low quality memes. Another thing about Plebbit is the karma system, which is absolute garbage. Unlike other websites where you can give likes/dislikes to shit and it won’t affect you really, On Plebbit if you get enough downvotes you can’t go on to most of the subreddits, and as such this karma system creates a horde mentality where if you say anything that goes against the mainstream opinion you get rewarded with a bunch of Downvotes, and people who don’t like this will continue to follow the horde mentality in order to get those sweet upvotes and Reddit gold. The biggest problem though is the censorship. Reddit is a heavily left-wing biased place filled with many left-wing subreddits such as r/BreadTube, r/latestagecapitalism, and r/politics and even the regular subreddits are usually filled with lefties thanks to lefty mods such as SlothOnMeth. It has gotten to the point where they will be completely compliment with Chinese censorship, where they will ban shit related to Hong Kong.
So basically TL;DR, Plebbit is a shithole that is the opposite of Free Speech, and all you have to do to prove it is just say Nigger or Faggot there and see the reaction.
