I think they're onto it, I think bookmakers are really prone to this kind of attacks. Also, I hope they fix some visual issues like the user said about the login and register not showing up at 100% zoom.
Maybe this was just a targeted attack? or is it their technical fault? because what I know is that every gambling site must have the strong security they have, but if this is an obstacle caused by people then I think we need to provide and how the developer must solve it quickly I know users really like to worry if there are problems they have do not like.
