There are so many watch lists maintained across the world. The FATF maintains one, FINCEN, and so does Interpol. Reportedly the FBI keeps getting 1600 new 'suggestions' everyday for its list!

We need a comparable list of Internet fraudsters. I guess it would run into a few millions!
Perhaps, the first thing CERN can do with their 'super cloud' computers is to collect the domains/addresses of ALL known fraudsters and keep them out of the Net.
Wishful thinking! I am sure the scamsters are already writing their emails - probably with the first offers to join the CERN network!
