I believe there are a lot of abusers. but have you checked scam accusations? The User deposited 1000 USD Worth of crypto and he got 1000 USD on Bonus balance. after that, he played a bit and withdrew the money. it's been 1 month he deposited that money. Do you know how to unlock the bonus? it works like Rakeback. That player didn't unlock a penny from the bonus balance coz he had no money to deposit for a month. He started a few ad campaigns on the ad networks. he got 113+ refs and suddenly BC Game blocked his account. So, How he abuse the bonus since he didn't unlock a penny in the last 1 month? in that period, he didn't deposit anything and he played with a daily spin only. This was the abuse I think.
They've replied the accusations.
I can say that when a player makes a large deposit during our deposit bonus periods to fill up their locked BCD bonus amount and then immediately withdraws leaving their account with only the locked BCD, that in itself is bonus abuse. Then, to spend the next few months only collecting playable bonuses from everywhere possible to chip away at unlocking the ill gotten deposit bonus amount is adding insult to injury.
They said only deposit and leaving the locked bonus amount is bonus abuse, and even worse he's only play with free spin, not with the real money. It's true they didn't specify this act is bonus abuse on their TOS, but it's suspicious that's why they claim it a bonus abuse. He's trying to maximize his profit, he only deposit to get the bonus and then withdraw his real money.
