It s shady as f..k to change ongoing rules. I understand that you have to fight people who use bots, but changing bonuses without announcing anything and randomly is not only unethical, but also shady. I understand that you are serious when it comes to paying people, but come on... I think this is one of the reasons people are using bots, more as a revenge for this kind of practices.
Changing how much free money we give away is shady and unethical? That's an interesting interpretation.
The botnets don't do it for any other reason than it is easy free money. When we change something to try and stop them (reducing the base reward) they change tactics and we have to react to that. A lot of these changes are experimental to see how they affect the statistics and see what the botnets do to compensate.
We try and make sure that our depositing and gambling customers are not affected by any restrictions. If you have never deposited then you most likely will be.
