Please be aware that they are a lot of free tips website/tipster/twitter earning affiliate commission rather than helping punter to win

'This means that when tipsters post their tips on social media, they include a link to the betting company's site. What is rarely made clear is that the tipster has a financial arrangement with that betting company, one which means that the tipster either receives a fixed sum for every person who creates an account with the firm, or more popularly, take a cut of around 30% of the punter's losses'
