So this source is likely a liar, uses insecure methods of communication (WhatsApp!????? LOL!) and sells NOTHING that we can't already get from secure and reliable sources.
Sounds G2G!
Here is a part of a info about WhatsApp and its safety, I took it from a news web site, should know about something before commenting imo:
"WhatsApp CEO and co-founder Jan Koum said that the company doesn’t have the information that has been requested, nor does it plan to change its position on encryption:
Yet again millions of innocent Brazilians are being punished because a court wants WhatsApp to turn over information we repeatedly said we don’t have. Not only do we encrypt messages end-to-end on WhatsApp to keep people’s information safe and secure, we also don’t keep your chat history on our servers. When you send an end-to-end encrypted message, no one else can read it – not even us. While we are working to get WhatsApp back up and running as soon as possible, we have no intention of compromising the security of our billion users around the world."
