Some server-owners are having problems with users lately, which write a book with click-handlers, for example a click-handler to execute the command "/op player". If your Admins are careless, they might get this book from the user and click on a line and OP them without meaning to. This plugin prevents that. Every time a user changes a unsigned book or signes a book, the plugin checks the whole book for click-handlers and prevents the change if there is at least one.
(Screenshot from a slightly changed client so i could actually send the json directly)
Just drop the plugin into your plugins-folder and restart the server. No configuration needed.
This checks only the normal user-book-update when you write a book ingame, books with ClickHandler can still be created per command or per plugin!
Works only with spigot version 1.8.0 and 1.8.3!
