Exactly. Proof by contradiction is a quite common technique.

That's the tinfoil hat version - and it highlights that the service has to be paid for somehow...

Thank you! Slashdot is now no longer broken from my point of view.

I was going to mod you insightful, but i accidentally clicked flamebait instead. In the moderation instructions it says that there is a "Normal" moderation option just so you can change your mind before clicking "Moderate" button. However, I did not see any "Moderate" button, the moderation was instead made immediately. As a last resort, I therefore post a reply here to make my moderation go away. Stupid moderation system, I know it used to work right once upon a time...
