What is the reasoning behind it, out of curiosity?
I understand there might be some issues when it comes to the infamous METAGAMING however I don't think removing systems from the playerlist solves the issue. While regions could perhaps be a good thing, the almost complete innacuracy of them (Connecticut being classed as Liberty, both Omicron Gamma and Alpha being in the same category, &c) makes it much less useful.
Also while some people might be able to quickly boot up into the game to just have a look at the player list with systems, for me the forum list was really useful because I didn't have to reboot into Windows or start up the VM to just have a glance at what's around, which as you might imagine is quite problematic.
Also, why was the cloudflare protection put on the player list?
