Are there still gamblers who use multiple accounts just to be able to claim the promos given by the casino because for now there doesn't seem to be any promos that are attractive enough so gamblers can take advantage of using multiple accounts.
You will, be shocked at the magnitude of greed some humans can have. Multiple accounting, even for promo bonuses that are unattractive, isn't something that is about to stop. There are other reasons people can also multi account, including trying to cheat in the referral program, evading bans or betting limits etc
multi accounts not only in casinos but even on all other sites that provide benefits such as referral programs, usually there are always greedy people who commit fraud by using the referral program, but usually not many get away and they are always caught committing fraud. usually the casino will immediately ban their account and their money is also frozen.
multiple accounts on gambling sites have existed for a long time and they are just irresponsible people who want profits by taking advantage of bonus programs and referral bonuses, that is one of the actions that is detrimental to casino sites.
but fortunately nowadays many casinos have a team or system to detect such a cheating system.
so any multi account cheating will be immediately caught by the review team and ban the account immediately.
