I was browsing when I saw an adsense (real google one, not anonymous-ads or what else) for butterflyllabs.com (note the double L in the URL)
They sell 3x600 ghs miners for
just 5,650.00, shipping "now"
I tried to buy one with fake data, they say to deposit 6.53230514 BTC to 16QkwrWv5MPoD7tfijSuJD2osdZJrXsCE2 within two hours or the order will be cancelled
After completing the fake order, every link will give a "you are banned" text
Be careful
