For sure you can't prevent anybody from doing what he wants to, but you can make changes more difficult.

Take a look at the DOMEvents, especially the Mutation-Events. Those give you the ability to see when something has changes(attributes, removed/inserted nodes, data in textnodes ...). For example you could build a function that watches some special attributes you would'nt have to get changed and reload the page, if this happens.
