In the Nick fandom Jerkass Sue and Draco in Leather Pants characters such as Sam Puckett, Helga Pataki and Jade West are far more popular and 'get away' with their Jerkass or Jerkass Sue behaviour by not being called out on it in the fandom while Megan Parker, Tori Vega and Carly Shay have been hated as the Creator's Pet, The Scrappy or suffer Designated Protagonist Syndrome. The main reason is simple. It's Shipping. The ability to ship these Jerkass characters is what determines how much tolerance the fandom will have for them.
