In the reading on Hate Crimes in Cyber Space, Danielle Citron describes incidents of cyber harassment:

“Their social security numbers and medical conditions are published for all to see. Even if some abuse is taken down from a site, it quickly reappears on others. Victims’ sites are forced offline with distributed-denial-of-service attacks.”

This action: the publishing of personal information such as home addresses, work addresses, phone numbers, social security numbers, phone numbers, etc is called doxxing. This action is meant to further harass victims online and in person/real life.
