Thank you, but as I said, my problem is not so much the tracker, Anton has provided me with good tools for that, my problem is to prevent them from coming back. blocking ip is useless, they change ip more easily than they change folders, ditto for email address. You have to be aware of one thing. Feeling scams report to the most talented of them 70 to 85000 $ per year. When you know that, you understand why they are sticky like bees on syrup.
Do not think that I am the only one and read this.

12% of the profiles are false
Figures that have something to turn out, but the social network of Mark Zuckerberg must also face an increase in the number of "Fake Accounts", duplicate profiles or false. According to Facebook, 10% of accounts, or 200 million, are duplicates and 60 million accounts are false (2-3%).

The ZeroFox study also provides a rather useful overview of the tactics used by crooks. One of the preferred methods of cybercriminals is to pretend to be an official financial institution, such as a bank or an insurance service. Hackers can also usurp others with identities, so be careful. For this scam to work, crooks will have to build credible identities. So that their victim does not suspect anything, they will work on their online presence, via an Instagram account, Twitter or Linkedin.
Once equipped with credible digital identities, the scammer will initiate the conversation with his victim, via Messenger or via Direct Messages depending on the platform. Aided by his later work and a fake website, he has no trouble convincing his prey of the veracity of his claims. Its potential victims are mainly those who are already in the financial world and who share with the false profile created by the pirates, centers of common interests, but they also target the more naïve and gullible users, such as people elderly.
