We have already talked about the simple fact that house edge is house edge and there is no way we could change that, you could have as many accounts or do as many cheeky stuff as you want and in the end we all lose money because of house edge. That house edge manages to make it mathematically impossible for all of us to lose money when we gamble long enough, if we keep constantly grinding and grinding, we will end up with losing a lot of money and that is the end of the story, no other way available.
However if you really want to gamble and win, the only method would be short bursts, like go in there, gamble all, win and leave. If you leave while you are ahead and not gamble again, you may actually end up profiting but that is the only way you could profit.
Well, with multiple accounts and against house edge results could be profit or loss, and if it is loss that is bad but if it is profit you get something, here you get something even if you lose which is great.
However how would you plan on trying to stop people from gambling with very very low odds of losing, like 90%+ chance, even as far as 99% if it is there (don't remember what the max was) and betting very small amounts and just leave it to automatic. That should probably give them a huge wagering amount without really losing too much money neither, it is still the same amount of money lost in the end, you will lose it all in the end, but it also allows them to wager more money before they end up losing it all.
What's good on having multiple accounts when you can have all that money betting in one account? You won't really have an advantage at all when you are betting with multiple accounts I don't see some kind of chance increasing in your way with you doing that. If where you are gambling is they have a edge then it will be guaranteed that house edge will be experienced by all of the accounts you are using.
