Taylor's mother meant that the "universe is open to everything you do online, everyone can see". This statement true, because people will hack your profile unless you label these as personal, even re-post material that you have shared.
In other words, we can say that a profile is placed on private in social media, it's not always free and your friend can use it, and they can share your personal information. It is difficult to uninstall once it is out there.
