Yeeaaah, I know nothing about hockey, so... no clue what you're talking about.
But, we have a lot of ways to assess how the mods are doing. Firstly, our own infractions. As a general rule, do I believe I deserve the infractions I get? Yep. Do I see generally decent members of DP saying they don't with any regularity? Nope. The only people I've seen saying that the mods are out to get them are the people the rest of us are surprised aren't already banned. If anything, the mods are surprisingly charitable.
We can also look at it like this: do abusive members last on DP? In most cases, no. Do respectful members last on DP? In most cases, yes.
We can see how the mods are doing by observing how DP is doing, and observing how people talk about their experience with the mods, and how the general culture of DP is working. Expecting the mods to list every infraction they hand out publicly is both onerus (c'mon, these people are unpaid volunteers), and potentially violates the sense of privacy of the poster. I don't think anyone really wants that when they look at the full implications.
There's no carnage to fix on DP. The general consensus of most of the members is that our system works quite well. That's why this place has been relatively stable compared to most other political boards.
