Lando is pretty pathetic lol.
Reminds me of when Wound tried to get my information but failed miserably and thought I was lying or something.
Lando is one of those type of people that are always looking for control over a person, and when they don't have it, they can't accept it.
Just laugh at him if he tries again.
If you've never posted your personal-personal info online then he won't find you.
