We can report the sources that are spreading these false stories. Social media platforms and other media outlets should not allow the spread of such invasive and untrue content. Also, as fans or just as respectful individuals, we can uphold the principle of respecting others' privacy and not be part of the rumor - mongering culture.
One should actively oppose such stories. If we see them being shared, we can speak out and say that these are untrue and disrespectful to Taylor Swift. We can also encourage others to respect her privacy and focus on her music instead.
We should simply ignore them. By not giving these false stories any attention, we prevent them from spreading further.
