Your activity is bad,
Like walk3r said, you are banned from ssrp for rule breaks so don't think you are ready for staff.
And you need to improve your application, like your disrespect part
I would deal with him like this:
Hey player, could you stop being disrespective/offensive towards [PLAYER].
If he then goes on he will be muted for 1 round and warned for Disrespect.
If he does it again i will simply Kick him.
And after that i will let an Admin deal with him.
You can't warn him for 1 round (You can but you need to unmute them) Most of the times if someone is disrespecting you will give him a mute for the whole map, after it it will be automatically removed.
