A well-known movie director went on the offensive after his teenage daughter was targeted by online harassment. USA Today reports that Kevin Smith, known for movies including “Clerks,” “Chasing Amy” and “Dogma,” went after one social media user in particular.

Smith, who cast daughter Harley Quinn Smith in a major role in “Yoga Hosers,” his latest movie, got proactive after a photo posted on Instagram by Harley Quinn prompted a profanity-laced tirade. The commenter wrote: “You’re ugly as s–t. And that steaming horse s–t of a movie, yoga hosers, should be banned. F–k your talentless c–t of a father for trying to compare it with the matrix. You’re cancer and I sincerely hope you end up like Lindsay lohan and dead.”

Kevin Smith responded by posting a screen shot of the message and writing: “What it’s like to be my daughter: 17 year old @harleyquinnsmith_ received this message simply for the heinous crime of posting a pic of herself on @instagram. Wow — way to unload on a teen girl because YOU have nothing to do in life.”

Smith added: “But even though I should be apoplectic about it, my kid thought it was funny. ‘I’d be mad if I had a tiny dick and anonymous voice too,’ she said, bemused by the bitterness. But here’s a nickel’s worth of free advice for folks like this Troll: if you hate me (or my kid) this much, the better use of your time is to make YOUR dreams come true, instead of slamming others for doing the same. The best revenge is living insanely well – so if you wanna get back at a 17 year old girl for the grievous crime of enjoying her life, the best way to do it is to succeed in your OWN existence.”
