I think it's still a violation of terms because you personally not allowed to use the casino full functionality otherwise your account will not be limited. Hiring someone account still pose some danger because your original account betting history is already marked by bookmaker and they will surely find out that you are using someone account by giving the bet result and bet type.
Will you mind sharing a sample bet that you are betting just to have a better picture on how you get that kind of messed situation.
You tell right about this apparently. Having to hire a subsidiary account from another user, either by just funding the user, maybe not directly and having the user bet on your behalf in a partnership betting agreement is also a violation of T&C for most and this is worst than being limited.
Actually, limiting an account is a proactive way to protect both user and casino/sportsbet so, users don't get to take so much risk that could result in adverse consequences and ensure that, the betting platforms are able to pay.
Winnings leading to ban is actually not cool and it tells what is expected of them gambling site with such policy.
Your offer though at OP could be r3fused non the less.
