First of all, I want to say that I am pleased to see you sticking up for your friend. It is good to see people sticking up for each other.
However... I'm afraid that I will not consider his unban on this post alone.
To refute the various evidences that you have provided, I will simply state these simple facts.
#1 Texture pack xrays DO NOT find diamonds for you. The only thing a xray texture pack can find is caves, and holes etc. They are highly effective at finding caves, and they are highly effective at finding hidden chests, dungeons and what not, but they do not work for finding diamonds that are hidden in solid rock. At least... they didn't work for finding diamonds in solid rock last I checked. The only way he could have xrayed for diamonds in solid rock was to have installed an actual xray mod, and this is the only way that I know of.
Do note that xray texture packs are indeed illegal, and I will not tolerate them, same as I do not tolerate xray mods.
#2, Showing a log of his entry into the server tells us little, to nothing. It does not tell us that he wasn't hacking, neither does it tell us he was clean etc. Most xray mods do not announce their presence on the console for obvious reasons.
In short, Me, Bee, and Owl were all watching F2n73, and we are all sure that he xrayed. We're not just 90% sure, we're not just 99% sure, we are all 100% sure. And if you choose to believe that we are dumb and stupid, the server was also 100% sure. Every single plugin and device we have installed on the server to watch hackers and xrayers was calling out telling us that he was xraying. In short, there was no way possible that he wasn't xraying.
He was looking through walls, climbing up a few blocks, hitting diamond, going down a few blocks, hitting diamonds, making weird turns, and even going diagonal to diamond deposits, skipping all else. If he told you that he wasn't xraying, then you can be sure that he is lying his face off to you.
In any case... I will consider unbanning him, if the following conditions are met.
#1, HE make a post... Not you King, Not another one of his friends etc... I require that the person banned make a post Him Self.
#2, He must admit to doing wrong, and he must ask for forgiveness. In such a case where Me, Bee, and Owl are all 100% certain, plus every plugin on the server, I will not accept the insult of being called wrong. The very idea that we'd unban him is based on the idea that he is sorry for what he did, and will do his best to not do it again. If he just goes spouting off that he did nothing wrong and that we're wrong, then obviously he's not sorry, and therefor should not be unbanned.
#3, The various people from Fenix MUST log onto the forums, and post to f2n73's unban appeal, asking him to be unbanned. I will only consider unbanning him if the populace of the server actually wants him unbanned.
If these three conditions are met, it is very likely that he will be unbanned. When he is unbanned though, all his land will be wiped, his money will be wiped, and his inventory will be wiped. He will restart as a wanderer. We do not take hackers/xrayers kindly, and while we will allow people who have hacked/xrayed back into the server on their first strike, we will not let them go by without at least losing what they hacked to achieve.
A simple guide line that we will most likely follow on all ban appeals is this.
#1 The banned person make his own post.
#2 He says that he is sorry.
#3 At least several people from the server making posts that they want him back.
On unban we will wipe all of the previously banned person's land, money, and inventory, he will come in as a wanderer, nothing more.
The first ban is almost always open for an unban if the previous three conditions are met.
The second ban is sometimes open for an unban if the previous three conditions are met, plus a waiting period of at least 6 months.
The third ban is permanent, and never to be revoked... unless severe circumstances are called in.
If there are any questions, feel free to ask away.
Sorry if I appear to be a bit harsh, but we will not accept xrayers, or hackers on our server.
