In my opinion, they can't make a different between the bos and real users who claim code manually.

If a user who claims code manually gets bad, there might be some triggered for their system to allert them or ban the account. In my perspective, if user who code bonus manually get banned (it's because claim code all of them successfully). They will think, no human can claim all the code in all time zone (there has gap on your sleep at least). That's the response they gonna to give from my perspective for user who got banned (even they're not botting).

That's how those work, basically you only can trust them (cause there is no 3rd parties can check the RTP). Or perhaps, play live games ? they have gambling fallancy for those speculation. Same way for people who gambling Black/Red with 50:50% chance, people will think streak lose will give you more chance. They don't realize no matter how much the streak lose they get, their chance is still 50:50 and previous lose/streak lose not gonna to raise your chance win.
