Yeah, I think the amount of non-fascist people has gone down since Musk bought Twitter. I anticipate it will continue with that trend. The process is not instant, especially when the platform is as pervasive as Twitter. But I think Twitter is a good demonstration of why moderation is a good thing.
And yeah, moderation is often not implemented in a perfect way. But I think Lemmy’s transparency (mod logs) approach is an improvement over traditional moderation.
