Seems unethical? Completely unethical! The ads are invisible so when they are clicked some schmuck has to pay for the click but gets no beneft because the user will end up on a site they didn't intend to go to and will kill the tab or click "back". Hopefully Adsense will notice a low time on page for the users and investigate. Advertising is awesome. It lets people earn and it lets people spread the word about their business ventures. Done right it's a win:win. Done the way the OP suggests it's a win:lose. I'm delighted that we all know that @MeinTraum cheats. People doing their due diligence on this user find it interesting.
