Aluminium foil shielding does work but only for a time as the perpetrators can move their equipment to another location. This is easily done if you live among dense housing which most people do. It's obvious the government's doing this as they're using allegations of mental illness as a cover. As the Wiki page says on the subject, "Psychologists have identified evidence of auditory hallucinations, delusional disorders or other mental illnesses in online communities supporting those who claim to be targeted." Just because some crazy people are saying this doesn't mean that all persons alleging electronic harassment are crazy as well, that's bad science. Also some of the stories you hear online sound concocted, possibly by government misinformation agents. It's a well crafted cover at first glance but when you start examining it more critically you can tell the whole thing is phony.
