It’s literally a flag in the account settings.
That said, I think mass copying of Reddit content is the issue. Functionally, yes, Lemmy and Reddit are similar. But they do have different cultures/subcultures. Even within a given topic, when you have both a subreddit and a community, they will like and dislike slightly different things.
I think the solution would be for individual users to bring content (links, memes, etc. - not comments or entire threads) over that they found worthwhile, instead of bulk copying.

Y’all nasty.
