Other, gambling sites, different rules of the game, the OP should try to be honest without involving a thousand accounts on one gambling site.

For now for me it has not crossed my mind to have more than one account to bet on gambling sites, just one is exhausted, What's more, you have to ask for other people's documents in the Kyc process, indeed some gambling sites don't care about that, but you have to be vigilant, if caught by admin / management you can say cheating / manipulating on their site.
my advice try to play and register one only, it may be more professional.
