This is because it’s emulating Reddit, and operates in the same ways, cultures, and countries as Reddit does.
From bad mods and bans, to niche communities, to the brigading and politics. From rating posts, avoiding discussions, and responding with meme floods.
Lemmy will merely reproduce all the negativity, politics, and everything else we hate about Reddit …and it’s already doing so.
[EDIT: As you can see in the comments, full of people agreeing Lemmy will also be toxic in similar ways].
I think the way to address this is to acknowledge, as a community, that dealing with the behavior of the worst people in the world is an evolving problem that needs to be continually, perpetually addressed if we are to have a sustainable internet community that isn’t awful to engage with. I don’t think it will ever be a truly solved problem, but I think there’s a lot of room for improvement. And it think it’s annoying, tiring, thankless work that’s very worth doing, and worth figuring out how to do well. The better we figure out how to have a nice, global internet community, the better all our lives will be.
