I tried the Loophole, and it worked for just one of my niche markets, on just several of the keywords I chose.
After it started to get a "buzz" about it, it didn't work for beans.
The amount of time and effort you have to put into it, the resources you need to spend on it, and the scripts you need to install, all for the trickle of traffic you get is *NOT* worth it in my opinion.
I have it, I used it, and in my opinion, its NOT worth your time and money.
I did learn a thing or two from my efforts, but all in all, don't waste your hard earned money, or your time. You can spend your money, and maybe get some of it back, but you can NEVER get your time back.
