I have worked in the sports betting industry for nearly two decades. Recently a good friend on mine had his offshore shop shut down in Panama. He had numerous affiliates working for him. One of them managed to get hold of a list that has a little over two million people aged 18-40 who have used a credit card online to make a deposit. I do not think the list is cleaned. I am not sure I want to pay all the money to have it cleaned. Is there some "black hat" way of cleaning email lists for less then the price quotes I have received?
