My suggestions about Mod apps:
1. look for creativity, as you have to be creative for some of the tasks as a Mod.
2. look for colorfulness, and alignment use; how long they have played the server; devotion for the position, and how they would use it.
3. look into how others interact with you, and how you interact with others; how long you can be online, or what timezone you are in.
4. look for how well you are liked, or how much you get yourself involved with events.
5. look into their history of punishments, such as bans, mutes, tempbans.
