tik tok users finding other users' houses

Not sure if any of you have seen this, but it showed up to me a few times. Someone makes a mean comment, user replies with a video supposedly showing the mean commenter's front house along with a hello kitty song, mean commenter deletes their comment.

I just want to know, is that even possible? Are these people using "1234" as their passwords for everything? Are they both faking it for views? What's up with that?
