StumbleUdon is back. Stumbleudon i a tool made by the same guy who made piqq.us, the only difference is it's an auto-pilot stumble exchange. I was using it before, but then it went down because SU changed some algorithms, but it doesn't matter, not it's back. Here are the invites: # 1015 http://stumbleudon.com/signup.php?r=40&c=2360p9d4lj47bfdd09e5 # 1347 http://stumbleudon.com/signup.php?r=40&c=24533t8qrr47c73ea996 Post your own after sign up, i don't need sign ups from my ref. links anymore because i've reached the maximum beneficial amount. I suggest you to open a new stumbleupon account for this tool, because if you have a "white hat" SU account, it might get banned. I use my only one and it's ok and never been warned So good luck. P.S. I must warn you not to submit any spam pages into the system, you will get banned for that.
