It seems most people are concerned with the lack of attendance you provide while claiming to be on the servers. You also mentioned this before:
because my playtime is low last&this week because of full time job.
Seeing as you have a full-time job and I'm guessing you've committed most of your time and energy into that, how can you commit to becoming an admin? (IF you were to be one)
From my perspective you kind of jumped out of the bushes and said "HEY, I wanna be admin" and not a lot of people have seen you active.
Plus zero for the time being.
