Like-Farming is creating a fake Facebook page to lure people into liking, sharing, or commenting on the same page. Once the page creators, called Like-Farmers, have gathered up hundreds or thousands of likes, comments or shares, they will change the page and promote something else, such as products that they will receive commissions for selling.
