Some server borders are visible in the Space map when you zoom in all the way, but most indeed are not or hard to discern. There is an easy way to know though, if you know just a little bit about the game's structure which you could acquire before demanding changes. Even more so if you actually want to effect changes.
Every map in the game, whether planet, space, or instance, is divided into squares of 8192 x 8192 units. If you've ever done any computer programming, you'll easily recognize this number as a power of 2. So, to know where a border is in any direction, open the Windows calculator, take your in-game position, from that take either longitude or latitude depending on your direction, divide the number by 8192, truncate the fractional part, and multiply with 8192 again. That number is your current server border to the left or below. Add 8192 (or just add 1 before the latest multiplication) to get the border to the right or above. In space particularly, it can be helpful to create waypoints of border crossings on your travel route (you know the /wp keyboard command, I assume).
This information is community knowledge but I can see how things sometimes are hard to find due to common keywords. But a genuine hindrance is if one doesn't make it a habit to at least try, and ask for pointers if that doesn't succeed. You set yourself up for backlashes if your mind easily latches onto the idea that something must change without making sure you are fully informed first. Many of us make this mistake sometimes, but learn to grow out of it.
