My question involves criminal law for the state of: Massachusetts
While my location is Massachusetts, the possible offenders are located out of state, and possibly out of the country.
Some backstory: a few weeks ago we ended up outing a person who claimed previously to have watched child pornography. This was on a public stream, and the person has since changed his story several times. Since we outed the individual as a possible pedophile, he has been attempting to DOX many of us who confronted him on the issue. The person claims to be a GS-13 in government service. However, knowing only his name and a possible last place of residence, I can find nothing more on him at the moment. This individual, working alongside his friends, have attempted to DOX myself to include my birthdate by using hacked information from some database, to include access to passwords. He has attempted to target family--and to date has failed, but he has done this to others and they have made death threats and the like to family members of other "marks".
My question is what should I do? Doxxing isn't a crime as far as I know, but I don't seem to have many choices dealing with this group.
