How did the anti-fraud center know that I was gambling online?

The anti-fraud center knows the reason for your online gambling. 1, sensitive data: This includes sensitive phone calls and sensitive text messages. These communication operators will have a large database, and the anti-fraud center will remind you when you receive a suspected fraudulent phone call. Another point is that your mobile phone network accesses sensitive websites or apps, because some apps and websites themselves are not safe. When we visit, Internet service providers will also upload this information to the anti-fraud center.
