Nice try steering the conversation away from the fact that you randomly ban people and you delete all negative feedback from your threads at will, without even replying.
And as for the arb part, it is so sad that both you and other bookmakers fail to realize that the more bets you have on your websites, the more you will grow. Why does it matter so match for you if I bet on X on your website and at the same time lay X on FairLay? Since you offer the odds, a "recreational player" (as you seem to define anyone who just loses on your website) could just bet on X without laying, how is that different?
Edit: As for snitching my IP and username, how hard do you think it is to restart my router, get a new IP and create a new account? Heck, you could even ban all of Greece, and I could simply use a VPN. See where I am getting at? Instead of spending so much time and effort trying to avoid the unavoidable, and naming each and every of your winning players a "non-recreational" one, you can just embrace the circumstances and make them work in your advantage.
