Yeah, i just heard a story recently about Archimedes, an old dude who lived several hundreds years ago and who was supposed to be very smart at his time. It seems that this guy Archimedes was a great scientist, and many people were coming to him to ask him advice about different problems they were having. But one of Archimedes's friends observed that each time he was coming to visit Archimedes, the front door was very hard to open, he needed to put a lot of effort into pushing it. So he asked Archimedes : "Buddy, you are a great scientist, but yet i am amazed that your front door is so hard to be opened. Why don't you use your mechanical physics knowledge and create an easier way to open the door so that we are not supposed to put so much work and effort into opening it?" And Archimedes told him:" Each time a visitor comes to me and he push the door, there is a set of levers and ropes in place such that every time the door is open, i get 1 square meter of my land dug. Since i am getting a lot of visitors, i do not even need to pay for digging my land anymore, since each of them contribute to it by pushing hard the door." I highly doubt that you understood my story since my english translation was kind of approximate, but the conclusion is this -it is very good if you can make other people work for you FOR FREE -it is even better if they do not even realize it. Yeah, so how i implemented this? Well i will be quite frank to you. I spam youtube and i need some captchas written when i create youtube users. This work was usually outsourced to a third party. On the other hand i just started my list building campaign (thanks to Ruck) and i get like 200-300 signs ups per day-email optins. So i thought, hey would not be cool if i ask the people to write a captcha when they are signing up for my list? And would not be even cooler if this captcha which they are supposed to write is actually a captcha coming from my youtube accounts, so that they can help me spam youtube better? Guess what, after a little bit of coding i get it done. Every time someone opts in to my list, he is asked to write a captcha. What he does not know is that the captcha he is writing is actually a captcha from youtube account creation which helps me spam youtube. It is kinda of cool, you know like i said: -having people working for you FOR FREE -they do not even realize it, they think that is a normal captcha, like a security measure. I hope this might give you some ideas guys.
