If you don’t want to see anything on your dash other than Harry Potter, blacklist these tags (these are the most common ones):

• THG (The Hunger Games)
• POBAW (Perks of Being a Wallflower)
• Game of Thrones
• The Hobbit
• Doctor Who
• PJO (Percy Jackson Series and The Heroes of Olympus)
• LOTR ( Lord of the Rings)
• OUAT (Once Upon a Time)
• POTC (Pirates of the Caribbean)
• TBBT (The Big Bang Theory)
• HIMYM (How I Met Your Mother)
• Disney
• Divergent (for anything related to Divergent and Insurgent)
• Other than these, I will put the entire movie title in the tag, such as “Easy A” or the actor’s name “Emma Stone”.
