I don't see the logic here.Outpost spam is becoming prevalent due to the low LY range preventing players from reaching systems they actually want to colonize means they need to chain dozens of trash outposts with zero functioning economies to actually place the stuff they do want in the systems they want to establish. Now we have a chain of abandoned gas stations everywhere, hogging systems others would prefer to colonize, as predicted.
Increasing the LY range will encourage players to expand out more and faster. If someone is concerned about '"station spam" and polluting the natural deep space environment, increasing the LY range is obviously not the solution!
Currently, with the 15Ly range the "station spam" will be localized around the bubble for a very very long time. To speed this up the LY range can be increased.
