It is worth noting that TheGooner’s website focuses around soccer (UK and European traffic) and not the US, which is what the majority of affiliates here are looking for.
Sportsbook.com should ALWAYS pay and play fair, but I am surprised about the post on sportsbook.com as I had a personal account with them a few years ago (no longer, as I decided I am a horrible sports bettor), and when I did and won money they paid promptly.
When Sportingbet sold off sportsbook.com for a pound, this was as a form of transaction, and yes the liablities were carried over, but this should not be a huge concern as sportsbook.com in its own right is a money making machine and 13 million is a drop in the ocean and standard business.
On the european side I work with Bet365, Ladbrokes and Will Hill! But my main money is derived from outside Europe, and my findings reflected this.
Just my two cents, and I still do feel at this stage the companies I suggested are solid one and not too worry about. Other companies I work with include Bodog and BetCris as previously mentioned.
