There wasn’t anything public at least, but they started a libel lawsuit. That was 2022 and no updates have happened since then, I can only assume the lawsuit was dropped or dismissed???
Either way there’s pictures of them keeping like hundreds of bras on their bus at a time when the majority of their fanbase was underage. I found a quote in 2015 by ATL on USA Today where they said they had 2,500 bras at a time. Article also says “If Barakat’s microphone stand isn’t covered in bras by the end of the night, he feels as though he’s had a bad show”
A user on twitter also said that at 21, Jack was signing fan’s breasts regardless of age and provided some photos.
