1. Have a profile picture
    It doesn't have to be of you, it can be of your dog, of your favourite flowers, of a celeb you love, or literally just a block of solid colour. If you don't have a profile picture, I immediately don't trust you because you're faceless.
  2. Literally that's it.
  3. I'm probably more likely to follow back blindly if you have an interesting username but honestly if you just like or reblog my lists or post a comment then your username doesn't even fucking matter.
