Everytime I see this on these forums I sigh. I seem to sigh a lot. Having been on both sides of this particular fence, I wonder, why is there a fence?
Let’s start off with the title. Have you considered why an admin has those powers? They likely are renting a server or have spent 2k or so to set up a dedicated server for your enjoyment. Whoa, your enjoyment? How about every member’s enjoyment? Have you considered your role and responsibilities while using their assets? If you have performed an action that is detrimental to others I see no reason that admin should not kick you. The vast majority of admins are reasonable people and will attempt to remedy the situation before banning. Work with them. Most likely they have a Discord server to enhance participation. It usually has a set of rules that define your limitations and the nature and purpose of the server. Have you joined the Discord and read the rules?
The next phrase also makes me sigh. “My admin is helping their friends”. OK, I help my friends. What is preventing you from becoming their friend? Is it because you have decided to play solo or separate your clan from the rest of the server, not participating or interacting in a positive way? Again, all while using the server admin’s resources of time and money?
These are just two examples of that ‘fence’. Mend it, or move on, or better yet, establish your own server and run it the way you want to.
My perspective, my experiences, only. I am not currently an admin, but play on a server whose admin (owner) I now call a friend. Try it, you may find it adds to your enjoyment.
