Wish you could explain the collusion and what the bots do. I guess I have seen a similar question in the past with an interesting answer that favours the use of well decentralized system to solve or reduce the problem.
Centralized betting platforms not so transparent, so expect to see such problems.
In Poker you can always have a bot telling you what is the best thing that you should do and act or think at your place.
In gambling games it's easy to secure because everything happen on the server. The player/client click on a button and it just tell to the server to run the game, nothing more, it can't be cheated (except if the developper is completely noob)
