1. Lying on an unban request doesn't particularly help towards getting an unban.
The book you used to teleport the giants did not lead outside the claim, it in fact teleported them 5 chunks into the claim, using the giants to kill him instantly clearly goes against rule 2 as you bypassed town claim protection.
2. What you say now and what you did kind of contradict each other. You say if you knew the giants had entered the claim then you would of removed them before hand. This seems like a load of rubbish to me. For one, why would you spawn giants near their base (even though this is a false claim as said above) if you didn't want them to kill the players? And two, after you had sent the giants to kill Ramma, you stated that your plan had worked and if he wanted more. This clearly shows that you intended for them to kill him.
3. I don't know where your clan members got the idea that the ban was for "spawning a giant". I'm fully aware of how it can be done, the ban was for using the giants to bypass the claim protection and kill a player within it (which you've admitted to)
Unban request denied, you clearly bypassed claim protection and then even tried to lie on your unban request.
