It would be better if you don't have many accounts, even if your goal is just to have fun, because as it is written in the rules of every casino that a person can only have one account. But many people abuse it because they want to get more bonuses and faucets and don't think if the casino finds out, it can block all of their accounts. And maybe that's why KYC began to be implemented so that each account can only use 1 identity. But of course, there will be ways for them, especially those who often exploit the abuse of bonuses and faucets, to get more.
I definitely agree with you that it is better to have one account instead of having many accounts even though I never tried having many accounts in a single casino. I don't know the other reason why they wanted to abuse it but I do know that they are being greedy which is very obvious. Well, they can only use one identity for only one account as you have said and definitely cannot use the same identity for the other accounts in the same casino which it will be banned or blocked.
The only thing I think about is that if they create more than one account, they want to use the affiliate bonus that is in the casino so they can get more rewards or prizes. And when casinos ask for KYC on some of their accounts, they can't do it because each account can only use one identity. Well, they could have borrowed someone else's identity and maybe that's what they used to verify their other accounts.
I remember one case - we have (or better say had) BetJa casino here. I dont remember conditions well right now, but users could claim 100 hourly; after 3 claims, to be able to claim more, user had to make a bet with an odd no lower than 1.4. Calculations are simple, claim 300, lose 100 (or win) and claim next 300. It wasnt states in rules how much you can claim from that faucet. Seems to be unlimted and free money. I did not succeed much, because there was a hidden and unknown rules, that after a number of claims, I got "you have claimed enough this week" message from casino.
What do you think, did I acted as an abuser, because I was technically stopped from getting free money? Was it correct for casino to stop me in that way, because to withdraw those "free sat", I had to make a deposit (and probably wager, dont remember that right now) ?
Yes, I remember that casino and it looks like it is still running today, although I don't know how it is now. I guess you are not cheating because you get that free money every hour and use it to bet. And although you can get extra free money from the faucet, it seems the casino has a way of stopping users from breaking the rules by limiting the number of "free sats" each member can get each week. And if they have almost reached the limit or have reached the limit, there will be a message like you said. I guess that's what casinos can do to limit cheating in using faucets and before we can withdraw the free money, we have to deposit some money and use it to bet.
