It never was a real offer, it was a 1st april fools joke, like the whole forum is!
But it's interesting that people would waste very fast 1000 to 2000 bucks for such wannabe LRL detectors and instead of scientifcally proving stuff first afterwards they start to think about using deadly revenge methods (of course this also was just 1st april joke... you have to believe that in a forum full of convinced LRL-disciples and ghost finders)
