I know this is locked but..
For a start, there will always be hackers. That's the truth of it. No matter how many staff you get, there will be hackers. We can't have a staff member following every single player, we can't have a staff member in every sky wars game. Even if we did, we'd have a lot of abusing staff. If a staff abuses, it gives an even worse image of the server that a hacker does. I would personally rather play on a server with a few hackers than staff who ban people for no reason.
Also, the system we have now is perfectly fine. We decide ourself within staff who becomes staff, and that works perfectly. No applications, people who deserve it may not apply, and people lie in them.
So, when you start complaining about how many hackers there are, think of this:
Would you rather be in a server with a couple of hackers, or a couple of abusive staff who ban and mute players for no reason, because trust me, you'd be more mad if you got banned or muted for a wrong reason and nobody believed you.
And then of course,
Quality not quantity.
