They lurk and then they complain if that makes sense. They only seem to do it if asked what they think about Lemmy though so at least it’s not everywhere. Usually people who were banned from Reddit and linger around her till it runs up or people trying it for the first time and disappointed no one is talking about movies or something so they can’t just get involved in a vibrant conversation.
I encourage them to get involved too, post what ever they like, to leave a comment nomater how insignificant it might seem. I get no response what so ever from them. I even make the point that reddit was this small at one point but it was the community that grew it.
