Yeah, stuff like crossposting is one thing. People do it across communities and subreddits, so may as well post stuff on both sites so you can get inputs from both userbases.

But the automatic copying stuff is too much. I blocked the lemmit bot almost as soon as it showed up because it became almost impossible to not see content that was being copied over by it.

Yeah there's something about the ratio of posts to active users. If it gets too high, there's just a sea of posts with comments too diluted. A lot of subs just don't have the users to support the same level of posts that equivalent reddit subs have.

It’s also important to remember too that while the vast majority of Lemmy users by far are Reddit migrants, just because you’ve seen something before doesn’t mean someone else has. Any bit of content can make someone part of the lucky 10000:
