There are some communities where most of the content is posted by bots copying posts from Reddit.
While the intention of the people running the bot is to generate more content while the community is small, from what I see across Lemmy, it looks like people tend to engage less with posts created by bots.
I was thinking about going this route, pass got me interested in the Proton ecosystem, was thinking about getting the mail plus subscription as well. But it looks like that's a no go :(
