You are preaching to the choir on the math. The fact you can arb with that bonus goes without saying. Seeing the bonus though I quickly figured this is like betting even money on their own markets, effective overround of 100%. Then noticed they use 1.90 at best on the 2-way markets that I looked at first. But still that's only a 0.50% advantage. If it was a onetime offer with with multi-account prevention I could swallow this. But the fact they fact they give you a bonus on every single deposit, no bookmaker could sustain risk management on that, and no smart player would ever bet their odds not having a bonus. This creates the situation where the site is left deciding after the fact what is bonus abuse and what is not. So my first glance opinion is that this is a scary site to bet at for players with a clue. My post was looking for specific examples of what constitutes bonus abuse (that part wasn't replied to) and if I got the example correct or not.
