Without any evidence no one is going to take this allegation serious, of course there have been some reports of bit involvement in the game process and the user overall experiences have been manipulated using some special tools like bots that you mentioned but none have been proven with any form of evidence.
So Megaplay will still remain innocent of this allegation until proven guilty and from the look of things, your claims lack that evidence to prove them guilty, but it is a good thing that we are discussing this so that gamblers will be aware of such possibilities.
I agree and the rule as we all know is to accusation will remain one unless otherwise proven. Proving this on the other hand won't be done instantly, there'll be a whole lot of process and that invomves the site's cooperation on this one. So I guess this would be inpossible. If ever Megaplay would be at the edge of being guilty, they can just abandon the gambling platform and make a new one under other people's names. If this is true it will be totally wrong and not only unethical 'coz it is a form of cheating on their end.
It's very simple to detect in case some gamblers don't know, when you make suspicious activities over the gambling platforms they begin to track and trace your steps till you're finally apprehended, I don't know how unacceptable is thebuse of bot on some of the gambling sites today than what their ToS clearly states on that, creating fake account with the intention of making an achievement will not last because the whole thing will later cast and be known, why are we then in rush from doing the norms in an absurd ways and manners that are provoking to hear.
Or simply move away from that site if you are being suspiscious of it unless your funds are being held by them. Ofcourse we would be wanting justice for those who were taken advantage of, if ever this is true. However that won't be too easy in web 3.0 for sure.
