Oh, it's too bad that this chatroom doesn't function anymore. I have met there many smart guys who told me about many methods to prevent fraud. However, I still have a contact with one of these guys named GarryH, and he told me about various modern fraud prevention solutions. As I'm personally the owner of a small business I'm really interested to protect my business from any kind of fraud. Gary recommended me to look at https://covery.ai/products/device-fingerprinting and I found their services really worth of implementing. Their products really helped me to protect my business and I'm looking forward to continuing our cooperation.
