talent as in hes good at finding people over the interwebz. he's done work for various agencies of the government and helped to find criminals who thought they were being anonymous on the interwebz. crimes such as child trafficking, gun trafficking, drugs...etc...prostitution...
if you have an ip and are looking for help to find out who this person is, all im offering is a potential solution. if not...no big deal...carry on. take it to the cops, as they will likely be able to offer you a solution as well. even if its a "private" ip.
