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.
There are indeed sites which do really allow to paste up some bot script for automation of bets and its understandable that they would really be banning out on accounts which does have suspicious activity in towards their site which is really a very common reaction.
We know that bots are never guaranteed things to make you profitable which this is really a very common mindset for those people who do really believe that it does really have that kind of winning chance.
Its for automation nothing-less but people are really thinking the other way around.
Of course, houses would really be against on something which could really be a reason that would effect their revenue.
