Spoiler alert: Spouting off "Avengers: Endgame" spoilers might send your loved ones and fellow citizens into a Hulk-like rage.

Citing Taiwanese media reports, the online news site Asia One alleged that a crowd beat up a young man yelling Avengers spoilers outside a theater in Hong Kong Friday night.

The story's already gone viral, although it's by no means been confirmed. The only evidence backing up the tale of vengeful Avengers fans is a single photo, reportedly posted on Hong Kong social media. The image depicts a man sitting against a wall, being tended to by onlookers. Not exactly concrete proof.

That being said, the issue of spoilers has persisted as fans awaited the highly anticipated superhero flick. "Avengers: Endgame" directors Anthony Russo and Joseph Russo penned an open letter to fans, asking them not to spoil the film for others. 

And plenty of fans have posted on social media about the lengths they'll go to in order to avoid seeing crucial "Avengers 4" plot points online.
