Aside from the obvious.
  1. Picture(s) of a pet snake
    Snakes are horrible creatures and should not be pets. Also, I'm completely terrified of them.
  2. "I hate cats."
  3. Nothing but selfies.
    Do you have friends?
  4. Bad grammar.
    "If your pretty, swipe right"
  5. "Just ask." / "Hit me up."
    Don't tell me what to do. Also, don't be lazy.
  6. Pictures of your vehicle.
    I don't understand caring so much about your truck or your sports car that you need to give it special billing in your dating profile. Why do you think I care?
