Earlier this month, Paramore's career-spanning bassist Jeremy Davis left the band. It was heartbreaking, and One Direction fans used the sad occasion as an opportunity to show their support. (If anyone knows great loss, it's them, this year especially.) Directioners came out in droves and sent loving tweets with the hashtag #ParamoreIsStillABand.

This weekend it was 5 Seconds of Summer fans who needed a helping hand, and the 1D kids were there to help.

The 5SOS boys are on the cover of Rolling Stone next month, and some of the story's details have sparked online controversy. The result was a worldwide #5SOSIsDeadParty trend, forcing their fans to defend the band they love so much. Directioners also stepped in and dominated the conversation, rushing to the defense of 1D's close friends and former opening act. Check out some tweets below:
