There are attempts to fix this via systems. I am to this day baffled what happened to Omicron Delta and that the Dev team let it happen.
Basically majority of Omicrons activity was concentrated into a circular system with high level missions where all interjected in the open middle. There was a freeport with chilling Zoners and rpand dangerous mining. It was so popular it attracted factions that had no business being there. You could blindly log any time of the day and get interactions, even with low server pops.
The systems people didn't like it. They wanted people to fly in more systems. They didn't want unrelated factions to come. They broke it up and killed omicrons for a very long time altogether, completely oblivious to the state of the server, living in the past, wanting to control people by breaking them up.
Now there are attempts to fix this - the omegas have been dead for years on end but Omega-48 is suddenly a top5 most popular system because of that simple design. People want to explore, people want to run many factions. But they also want to log without sciencing player list and interact right away. Creating these activity hubs, one per region, with pvp, PvE, mining and a rp hub for is a good answer.
