Or you just redistribute the winnings for the bots to the other lottery ticket owners of that week, a re-raffle.
That was my first idea then I realised that with the ticket database being full of bots we would just end up with another set of cheats winning.
What about a lottery by deposit in a certain period or have you found that the bots deposited?
I suppose what ever the suggestion to redistribute sadly will have a botting potential as it's something of monetary value.
The only thing that kind of doesn't have monetary value is the reward points.
