Miami Hater Girl

 Miami H8ter (Hater) Girl was a blog secretly run by the hater Tilly Thompson, under the anonymous name, "H8ter Girl." The blog was about what she hates, enjoyed majorly by Trish because it's "hilarious". She also watches Austin in disguise, sees him do something, and turns it into something bad even if its not.

In Bloggers & Butterflies, Tilly hates on Austin and posts embarrassing photos and videos of him on her blog, such as him eating a "pants sunday", embarrasing himself in front of a girl, and editing a video of Austin pulling Nelson out of the fountain, to seem as if he is actually dunking him in.Tilly has tricked Dez into giving her embarrising pictures of Austin.She later shuts it down after she accidently admits, on the stage in which Austin performs The Butterfly Song, that she was the one whom was running the blog and spreading bad rumors about Austin.

Later, Tilly admits she thinks Austin is talented, and she doesn't hate him, rather than Ally after something that happened in kindergarden. The class was having an insect-themed play, and they had to write a song for it, and let the class choose who's was better, Tilly's or Ally's. Ally's song, The Butterfly Song, won over Tilly's song, The Ladybug song.
