If I am understanding properly, this is suggesting that Snowden had a form of backdoor access to Twitter and FB.
Hidden messages being left in deleted or altered tweets? I occasionally do something similar on boards where admins can see deletions and alterations. Write something, then delete/alter. Only visible if you happen to be paying attention and archive within the time it takes to alter.
Snowden worked with Prism. That is some back-door stuff into internet databases and access logs.
An elite hacker… No. But when you are one of the ones with access to privileged information and can steer design or even directly implement coding solutions … You can leave handles that will take entire teams months or years to analyze and identify just what the hell you did and how it works or can be exploited.
Because Russia would not let him in?
If he got into Russia and then leaked….
But the op seems to have hit a roadblock and they improvised a way to try and still make Russia into the bogey-man.
Possibly as leverage to try and buy his way into Russia, as well. Perhaps he got a little squirrelly on his handlers and panicked.
Either way… I got to go do some manufacturing. Thank you for the industrial work and the protection of American steel. The Vietnamese do not know how to hold an alloy to save their lives.
