Yahoo is losing user's faith day to day by a Reuters report that claims that under classified directive either from the NSA or FBI ,Yahoo built a software program that secretly scanned millions of user's mail account. But what they are looking for is unclear to all of us

The company accumulated with a categorized US government directive, either from NSA or FBI scanning millions of Yahoo Mail, two former employees and a third a person who knew about the program told Reuters.

Yahoo Transparency Report has called Reuter's reports "misleading and denied about the mail scanning program exist, Yahoo is a law abiding company and complies with the laws of the United states". However, the former employee of Yahoo told Reuters that security specialists were disabled the program after discovering it.

Andrew Crocker, staff attorney with the Electronic Frontier Foundation, said: "under the section 702 of the FISA Amendments Act, which permits the government to target on -US citizens abroad for surveillance."

It is not the first time that Yahoo has been accused of providing user's data to NSA. In 2013 former CIA contractor and whistleblower Edward Snowden revealed Yahoo involvement in the NSA PRISM surveillance program. Under this program, the government collected data from several technological companies including Google, Microsoft, and Yahoo.

Some surveillance experts said this represents the first known case of a US internet company pact with a spy agency's demand by searching all arriving messages.

Reuters was unable to determine what data Yahoo may have shared to ,and whether intelligence officials had approached to other email providers with this kind of approach. But the officials of Google,Twitter ,and Microsoft have also confirmed by a press release that they haven't scanned user's mail like Yahoo.

Yahoo's decision to comply with the government's surveillance will likely be a source of much debate. Earlier this year, the government asked Apple to access the information in the iPhone used in Sun Bernardino terror attack.

Edward Snowden , former NSA subcontractor tweeted, "Use@ Yahoo? They secretly scanned everything you ever wrote, far beyond what law requires. Close your account today"
