Hello guys! I'm new to BlackHatWorld, and I'm really thankful for the guys who post useful threads. You are the best!) Yesterday I've been doing my homework (Microeconomics). Some of the exercises were too difficult to understand, that's why I've decided to search the answers on the internet, and most of them were from Course Hero. Those who don't know, this is a website, where you can find useful resources for your study and find help with your homework. If you want to have an access to the documents, you have to pay about $40 monthly or $120 every year, which is expensive for students. In addition, they don't want to pay $40 for only 1 or 2 documents. Then I've found, that some guys buy premier accounts for $120 and sell the documents to students for $2-3 for 2 documents or something like this. Now I have an idea. What if you buy premier account and give documents for free? The only requirement is that they have to sign up somewhere, take a survey, etc. So you got this - some affiliate stuff.
