I have no idea what makes you think from that screenshot that we can blacklist whoever we want for whatever we want.
Here's my take.
All SMT at Gaminglight has put in their share of dedication, hard work, and perseverance towards their server. Because of that, they are trusted at their positions and are trusted to make the right decisions as best as they can. That is why they are allowed to use their powers, as they've put extensive work in bettering the server, so for some, it serves as a reward for their work. With that being said, I do not think that these "Guidelines" are really necessary. What it really comes down to, is judgment. For example, I will use the situation you included in your post. Some people may say that Spection shouldn't have done that and he went too far, some people may say that he was justified in his actions. What really matters though, is whether or not Snar (or Zeeptin) thinks that he went too far. The manager for whatever server the SMT report is filed on takes in all aspects of the situation and determines whether or not that the SMT member went too far.
I trust all of the Gaminglight SMT, and I trust them to make the right decisions with their powers. However, all of you need to remember that we are not robots, we are humans just like you. Which means mistakes will be made. I know it's easy to hop on the hate train as soon as somebody makes a mistake, all I ask is to try to understand that we are not perfect either.
So overall, I think that more faith needs to be placed in the judgment of SMT members. If an SMT member does something that you think is wrong, by all means, report it. But the manager may have different viewpoints than you, so please try to understand that if your report gets denied, there is a valid reason for it.
