Being a music fan is hard. One day you're bopping along to your favorite artist's music with millions of other fans, the next day you're defending them for plowing their car into a crowd of people. Sometimes you just have to let go because the music stopped being good, or their name came up in the #metoo movement. Unfortunately, if you're not careful you may still have the remnant of your fandom, like a tattoo or a screen name.
I don't know if BiebersGurl4ever1 forgot that her nickname had Bieber in the title, or she just hoped nobody would notice when she posted that she doesn't normally listen to Justin Bieber. What? Are you a fan of Justin's humanitarian work instead? I think it's about time to change the username, BiebersGurl. Some things don't last 4ever... 1.
