That's because Kesha has an ambiguous Instagram username that 80% of people don't realise is official. I mean, really? iiswhoiis. It's not even similar enough to We R Who We R for people who knew that song to make the connection. She's always had such dumb social media names. Like, this is 2015. You must know that social media is a big part of an artist's connection with their fans, and part of what sells music. Ugh.
