They have no way of knowing you are telling the family member or friend to take advantage of a promotion. Then helping them play through the promotion. They could never prove that. In the TOS of every casino is a clause on abusing promotions, it's there, but unusable, they just have no legal ground to say we put out this promotion to lure you in but now that you have beat us on it we won't pay you because you abused the promotion. I've been doing it for years and have never had an account closed down. Which is all they could do, say thanks but no thanks we don't want you playing on our site. The abusing promotions clause it's the #1 laughable thing the house cries about. State reps would pass laws instantly to protect the consumer if the house ever really tried to stop abuse of promotions. And the house knows it, they are tightening up on promos and playthrough contributions. Draftkings just made a list of high RTP machines and now only count them as a 20% contribution towards playthrough. I peer all terms thoroughly, this promo added up until I saw this then it went down the drain, this is the first time I've seen draftkings do this.
Yea gnoming is just a term, totally unenforceable by the casinos unless they can obtain video of the individual actually playing the promotion for the other person.
Just in the last couple weeks I helped a buddy in New Jersey make 6 grand on New player promos, in casino and hedging risk free bets, all the money has been safely withdrawn and i recieved my cut. Cheers mate.
