Hilary Duff’s prankster husband Matthew Koma is going to have to find another platform for his jokes after being permanently banned from Twitter. The producer couldn’t help it after the Gwyneth Paltrow trial that captivated the world, and he used his account with a blue checkmark to impersonate the actress.Elon Musk implemented a strict no-parody rule unless the account has the words parody in it. Koma changed his profile picture and name and began responding to tweets as if he was the Goop founder.
