OP is not here to provide any service, or join in earning from the forum through a signature ad campaign since he already got more than a million dollar and have retired, so, ban-evading is nothing.
And besides, if I was him, I possibly would have done exactly same thing, which is, register a new account to share this type of information, for there could be a million ways to trace back to who he is if he had used his main account - trust users of this forum on that, most especially, if he had done the wallet signing most of us do for the security of our accounts, or participate in a signature or bounty campaign in the past, wallet address he used for this activities can easily be tracked or traced, and by so doing, there could be a way to find a link to his current wallet where the stolen funds are held, and this could jeopardize everything for the op.
If I was op, assuming all he said here is true, I would not have bothered creating this thread, it's absolutely not necessary.
The acclaimed millions that the ops mentioned in the post may be a way to attract members into contacting him, and he may not have won anything at all, what I think the ops want to do is to deceive people who are greedy and looking for a way to cheat to gain who may reach out to the ops and at the end he demand for them to pay a certain amount in fees to be able to have access to his so-called formula which at the end may end up to be a lie and scam at such.
I don't believe any casino will allow a bug to exist in the system for so long to the point that a player will exploit it to make such a huge amount of winning using the bug to cheat the casino system.
