Reportedly, the NSA will inform the Russian people that they will make a public tweet as a sign that they want to establish a relationship or to prove that they are willing to discuss further.
The tweet was delivered throughout 2017. Some of the tweets look as though the NSA is promoting itself, while others support the rules that allow the NSA to spy on people.
There is also a message disguised as a tweet about historical facts, such as the 177th telegraph patent celebration. It is not known how much comparison between NSA tweets make as secret messages and regular tweets.
