I knew they never closed the P.O. Box. Like someone said above, they would never give their home address out to the theme parks, hotels, etc. so they still needed some place to have companies send travel stuff, swag, etc.
This newly revealed lie reminds me of the one that has been talked about repeatedly on Guru.
Back when they did their first-ever Disney cruise, they harped from the very first video revealing that they got #hosted for a Disney cruise that it was Jenn's first-ever cruise and she was blabbering on about being so nervous about what to expect, being on a ship, how she was going to feel, she asked friends what it'd be like, what to wear, etc.
Multiple times during the cruise vlogs, Tim would ask about it being her first cruise and how she liked it.
At the end of the cruise, he asked - now that you've been on a cruise, how did you like it, blah blah blah...
EVERYTHING giving the impression we were watching things through the lens of someone who had never cruised before - Disney or otherwise.
Then, when they did their recap video, the first things out of their damn mouths was literally - "you know how we said it was our first cruise? well, actually we have gone on a cruise before but that was like 20 years ago and so it doesn't count."

they are such liars.
