There was recently a discussion about this from someone who crossposts stuff from reddit to lemmy and got banned for it. Opinions vary but it's mostly anti reddit. Can't find it now though. Myself I'm not sure. Importing trends and "reinforcement learning" or manufacturing cons(t)ent from reddit is problematic. But it's not like most lemmies aren't already trained like good little dogs to be neoliberal imperialists. I mostly see the same shite trending on lemmy as on reddit.
It definitely is hilarious that the top post on lemmy currently has double banned tags lol
