If there are people who try to abuse, I'm wondering what kind of people they are who want to spend their time for $5 in a month. Even if people try to abuse it with multiple accounts, I dont think it will be worth their time too unless they can create a bot that can claim the free cent automatically and can be implemented with multiple accounts. Lets say they can create such bot, I'm sure the security system in the casino will detect it and all the accounts will be banned.
Well, we don't know how they abused it but what is certain is if they can abuse it to the point of making 10 accounts, that's equal to $50 a month

Creating a bot might be worth it for them to try because using a bot can make it easier for them to claim the reward. But I'm sure the casino must have prepared a way to block the use of bots or anything that can abuse the bonus.
Maybe I'll try to register and look inside to find out what features have been applied to the site. And for those who have tried it, I'm curious about the results.
