Mr. Robinson said in an interview that that he has been tortured and abused by gang stalkers and by “neurological weaponry” since leaving the Navy in 1982. “To read the stories and the similarity of the harassment techniques that were going on, to hear about the vandalism, appliance tampering and all the other things were designed to drive a person crazy, who do you go to with this?” he said. “People will say you are delusional.”
For Mr. Robinson and several other Web site users interviewed for this article — all of whom insisted they were not delusional, including one man who said he had been hospitalized in psychiatric wards — the sites provide the powerful, unfamiliar experience of being understood by others. 
“By and large, most people are sane and coherent and can relate exactly what’s happening to them,” Mr. Robinson said. “They can say the things that would otherwise get them labeled as delusional.”
