Method is prolly strictly linked to making people register on betting sites and use their own ID (but telling them you won't have to access their accounts) and then having them use the bonus and eventually pay it out.
Methods like these are not easy they are linked to heavy social engineering - Just "speaking their language" isn't enough because we all know you have to make them fill in their ID data, even on very popular betting sites they would be very vary, now think what if we have to direct them to some shady site, that's double the weirdness because people would be afraid their data would be leaked.
Do not call this easy method please, unless you can in full honesty state that this method doesn't revolve around making people sign up for betting sites using THEIR OWN personal data.
