Everyone, admit it: You’ve stolen wireless Internet before. And although popping on to some poor sucker’s unsecured network to BitTorrent last night’s episode of So You Think You Can Dance? is one of the Internet age’s great semilegal pleasures, having people ganking your wireless only impedes your God-given right to free dance-based reality-show downloads at a reasonable speed.
Yes, you could always just enable encryption on your router to stop casual users from freeloading. But instead of simply locking them out, wouldn’t you rather have them questioning their sanity by, say, redirecting all their traffic to kittenwar.com? Or by flipping all the images they see upside down, or making them all blurry? With a little Linux hacking, this guy split his network into two halves—an encrypted half for himself, and an unsecured, tweaked-out half for the Wi-Fi thieves. A pretty ingenious prank, if you ask me, especially if you have thin enough walls to hear your Interweb-stealing neighbors wondering where their marbles have gone. —John Mahoney

There are much better things to do with those who would steal another's bandwidth.
A little use of an appropriate application such as aeropeek or etherpeek to monitor all the traffic on your home network and you can quickly gather lots of great information on your neighbors as they criminally steal your information. If they didn't want me to have their e-mail addresses and personal information they should not have come into my house and gave it to me.
Better yet you could re-route all their traffic to websites known to have all kinds of nasty activeX virii and the like on their pages. That is always good fun as well.
I meant to say criminally steal your bandwidth not information.
YOu are not a very nice person, Patrick. What happens when you infect their machine with a virus, and, like they turn out to work for NASA and then they take an infected flash drive to work and two satellites crash into each other just because you decided to take the law into your own hands? Haven't we learned anything from Batman? A vigilante is just one man, who can cause more harm than good. To truly make a difference, you must become a symbol. A symbol of upside-down Websites and blurry images. Jeeez.
How is someone supposed to know they aren't allowed a slice of your bandwidth unless it's encrypted? There are many people who are just fine with others hopping on.
lol...funnny
nice idea tho, although I steal bandwidth myself (occasionally, and only from the weird guy next door) the world could do with more such revolutionaries.
hats off to thee my man.
If you encrypted your bandwidth your wireless network will not have people "piggy backing" on your network!
nice article
Someone needs to tell me how to do this because i am to lazy to figure it out myself
