Gambling bots are equivalent to high yield investment products, there is simply no way for them to work in the long term. A company that is consistently having to pay out winnings to a gambler would go bankrupt - the most simple line of logical reasoning you can apply to somebody claiming to have a working program. Any responsible company heavily monitors their player activity and would quickly shut it down. Only someone who is clueless about technology would believe that exploits could run for a long time and even if you got funds into your account it would be heavily scrutinized at the withdrawal stage.
I believe people offering bots services with guaranteed returns are doing this on purpose of scamming naive and greedy gamblers for profit. This includes hypothetical scripts promising to cheat online platforms in order to assure profit to players. In some cases I see gamblers who lost money they shouldn't have wagered at first place selling these 'money making methods' ahead to another gamblers in a desperate attempt to recover every funds they have let gone. That is, to not take responsability for their own acts and prejudice other people to recover their personal losses.
