Is it safe to say that photo filters help deceive people's looks?

My best buddy has been dating this chick online for over 2 months. They finally decided to meet up, oh boy! The person on the picture looked nothing like her, her natural skin colour is a beautiful brown and she manage to whiten it with filters. She's actually twice the size of the person in the photo. She gave herself a photoshop surgery. He was so sad because he fell for her quirky personality but the whole appearance made him felt betrayed.
