The Huffington Post has claimed that the National Security Agency has collected evidence of online sexual activities and visited to pornographic websites as part of a proposed plan. It was aimed to harm the reputations of six people the agency considered `radicalizers', citing documents released by former NSA contractor Edward Snowden.

It was said in the report that the targets in the document are described as examples of how personal vulnerabilities can be learned through electronic surveillance. It was used to undermine a target's credibility, reputation and authority.

Viewing sexually explicit material online is among the vulnerabilities. To make it worse, they used sexually explicit language while communicating with inexperienced young girl, said the NSA document, dated Oct. 3, 2012.

The document did not make any accusations of the six individuals targeted by the NSA for their involvement in terror activities. According to the agency, they all are currently residing outside the United States, reported HuffPo.

Privacy International said: "This is not the first time we've seen states use intimate and private information of an individual who holds views the government doesn't agree with, and exploit this information to undermine an individual's message". The report came up immediately after a group of United Nations experts adopted a `right to privacy' resolution.
