Whether a lottery is run by the Government or a private company, frequent audits done by disinterested parties should always be done. The only trick is to make sure the auditors are indeed disinterested.
A good suggestion of yours, the problem here is being corrupt staff on lottery gambling and maybe there are too many of them inside of the company which is they can negotiate others to become one of them. Money is powerful and even us, we might be tempted if someone offers on us with a high amount of value just to make our mouth shut. Auditing is good but I think this time that they must use blockchain technology which having transparency and will detail all of transactions activities.Something like this isn't going to be as easy as you say it is.
Thing about a reputable company who does audits who is hired to do something like this -- a lottery audit account isn't worth that much, so they're not going to jeopardize their company -- and jail time for the people that are involved, just to help someone else out (or to make a small amount of money for themselves)
It's not worth it. Audits are helpful and they do a very amazing thing if done by a reputable company.
