Try to go a little bit more in depth on the questions in the format. For an example, you can talk more about what servers you were staff on even though they weren't fully released.
You can also go a little bit more in depth on about the reasonings behind the bans you had and how you have recovered from them.
Besides needing some more detail and having minor grammar mistakes your application is overall pretty good. Once edited and tweaked a little bit I will re-read your application and reconsider my current stance. Good luck!
