Jingl After much research and a lot of exercise for the little grey cells I have cracked it and found the answer to your question.
It is not fairy dust at all. I was mistaken. Sorry.
On the desk at GNHQ is a small red button. Pressing it deletes a condemned post.
Beside it is a large red button. Pressing that one deletes a whole thread.
Under the desk out of sight is an ENORMOUS red button, which can be reached secretly with a knee if the office is stormed by a mad spammer intent on infiltrating GN from the nerve centre. Pressing that one opens a trapdoor which deposits the intruder into a dungeon where the intruder is trapped watching repeats of "Extreme Couponing" until they repent and promise to mend their ways.
Ooh no, I think MrWotsit was offering more of a 'How to Get Your Loved One Back' and 'Get Your Parents to Approve of Your Loved One' service (at a price, I'll bet), plus various witchcraftery options which probably don't bear thinking about!
