Isn’t scamming like the second major thing that brings outside attention to Eve, after the big nulls wars? News of big scams leaks out into the wider gaming media, even the mainstream and is a core part of the game.
Scammers gotta learn there trade somewhere so why would you want to do anything to stop that? Not that deleting local chat would do much in my opinion.
I thought the charm of EVE was that these scammers are accepted as part of the ruthless EVE universe. It was one of the things that drew me to the game, a universe where pretty much anything is allowed including killing others in ‘safe areas’ and scamming them. A universe where I had to rely on my own brains to survive, and seeing those ISK spammers in local is a lot less annoying for me than seeing them in games where it isn’t allowed, but they do it anyway.
Because you’re not going to stop scammers from scamming, even with heavy moderation. Why not include them in your game lore instead?
Either way, your proposed change for local (remove chat, keep member list) is the opposite of what I would suggest for local (keep chat, remove member list), but I guess that’s a different topic.
