TOPIC: Why cant you be staff on other servers?

I have been here for a long time and I never got told WHY people cant be staff on other servers, im not trying to start drama or shit like that I genuinely want to know why <3

Thanks in advance, also once there is an answer feel free to lock/remove this <3

Mainly so you focus on this community, rather than others.

Other servers don't allow it either. It's for trust and dedication
