[Matt3o12_]

That's not the point. You do not design your server in a way that it is easily hackable because people can just set up their own server and not destroy something else.

I wish we lived in a word where that is not necessary and all human beings work together instead of against each other. But we do not live in such a world. Creating valid thread models and pointing out disatantages of systems that malicious parties will exploit is therefor necessary.
