I think Peaches would be a good veteran. He is an old player, so he knows the ropes. He hasn't done anything that bad that would give him a -1.
However, I do not feel that your personality fits an admin. I personally feel that admin should be more mature and less hot headed when it comes to certain situations. when An admin should be representing the community, and shouldn't show any sign of toxicity towards others. Veterans, on the other hand, still represent the community but at a lesser extent so veterans should have more leisure. (I don't know if worded this right, I suck at expressing how I think in words.)
In other words, he should be a veteran but I wouldn't agree with him staying an admin. Just saying my opinion.
