If the bot uses does not make a script inserted with the game like makes the manipulation in the game there's nothing to worry about it but if there's some manipulation like injecting scripts I guess it quite gets trouble, if the bot is just used to make an auto clicker and bet I guess it is just okay because it does not make the game manipulated. Always check their Terms and condition and their FaQs to make sure it does not bring trouble if you would like to use one.
I think that is the first step people need to do, I suppose that some casinos will be fine with a bot that just lets you click faster but without a doubt all of them will be against any bot that may try to attempt to mess with their code or with the results themselves, many people do not take the time to read the TOS but in this case it is really important as no one wants to lose their casino account they have been building for months or even years just because they downloaded a bot from who knows where.
^ I have this question in my mind and since I did not a fan of this gambling bot I become curious.
How do we determine that the bot did not have the script injected? Because sometimes I am thinking about using a bot but I am always worried about their legitimacy. However, that is a good action while encountering a new gambling casino, always read the ToS to stay away from troubles in the future and avoid violating their rules.
