I used the command to enchant quite a few books with more than one enchantment, so I probably had around ~80 or so total books enchanted. I have around 20 of them left in a chest in my home, the rest I used on my tools and weapons.
I do consider books to be semi-valuable, as I live out on the edge of the map, and rarely trade with others. The mob drop buff does help quite a bit, but I rarely harvest leather, and as a result, most of the books I made, I enchanted and used immediately.
I did die at one point and lost the books I was carrying, as well as quite a few enchanted tools and armour. At the time, I also had 7 legitimate books with me that I was transporting to my nether base.
I do not recall any trades involving enchanted tools or armour that resulted from this command, And I did not give, trade, or sell any books gotten from this command.
I did not realize this command was not a "feature" of the server, and I am sorry that this is the result, but I am willing to make up for my actions, and am fine with having all my enchanted items confiscated from my inventory and my chests. I just wish to be able to play again.
