Difficult for harmless citizens to fight slander of CBI, security agency employees

One of greatest problems faced by domain investors is how CBI, NTRO, security agency employees allegedly on the payroll of google, tata are allowed to waste infinite tax payer money to slander harmless domain investors, making up complete fake stories without any legally valid proof. A domain investor has been under surveillance for more than 7 years, as CBI, security agency employees stalk her, find out who she has contacted, so that they can mislead or dupe the person with their complete lies about the domain investor.
Other than helping google destroy the reputation of a competitor, cause financial losses, no one is benefiting from the slander, yet it continues for more than 7 years since 2010.
