I am just a normal programmer, not a spy. Visa application is acceptable (I have done that in the past), forging social media accounts is not (I in fact I do have FB account but God knows where the password is).
I think the point they were making was that regardless of how you feel emotionally about giving up specific information, it has no effect on whether a country allows you to enter. So go ahead and do only what you feel is "acceptable", just don't be surprised when you are turned away at the border for not filling out all of the required documents.
