My only issue with you becoming staff would be your attitude towards other players, especially ones you aren’t a fan of, as well as the perception you give when you make jokes that are a bit too edgy. You make a lot of jokes that are borderline NSFW or toxic, and as a player it can be a bit of fun but as staff it would only let mingey players think that it’s okay and they will take it too far. As for your attitude towards other players, I feel as though you can get vindictive towards players you don’t like, and that can lead to being a biased staff member.
I think staffing would be very easy for you given your time played on the server, and I think you’d do great as long as you keep in mind what I’ve mentioned as well as making sure you are the only one using your account.
