Why does Brave allow Scammer Ads like BitcoLoan

#BitcoLoan Scam - I kept getting these ads for awesome rates, while using Brave, about BitcoLoan. So, I thought Brave was selective about who they allow to use their platform for advertising and decided to check it out with minimum amount for deposit.
