I am pretty sure that it is hard to "prevent" bot but it is easier to punish bot. How? Well, you can't check every single person who wagers, which is an impossible task because it is highly unlikely that you will face any problems in that many bets, you will see only a few, which should be bots, why check one in a million when you can check one in 50k? So that means you check after people win, and after they win you don't check all of it, which drops the number even more, you only check the ones that do not have KYC that do not have any patterns before and so forth.
That leaves only the people that ended up winning and also looking shady, and that is the only thing that really matters. Which is why I personally believe that we should be understanding towards the casinos who take the bets of bots, but also bans them after they win, it is easier that way (and profitable too).
That's a bit cheeky though isn't it? I am not saying it is wrong, it is obviously not wrong because that is the correct method that almost every casino uses. So how can you really blame bitsler for something that every single other casino does? That is why I am not saying it is a wrong thing to do by bitsler. However even though all casinos do it, that is still a bit cheeky isn't it?
It is basically something that bitsler and all other casinos does but at the same time it should not be that way, there should be "prevention" before it even happens. Think about it, you let the shady people gamble, if they lose then you get to keep their money, and if they win then you say they tried to scam and they end up still keeping the casino as well. So long story short casinos get to keep all those scammers money anyway, instead of preventing and that is a bit cheeky, still quite fair grounds though.
