This was something that was never addressed in the show, before someone starts running pointing fingers and ranting about conspiracy theories. It's something I was thinking about.
The events of that night were more than just Juliette betraying Kelly and Nick retaliating. All of the sudden Meisner's in the picture. Juliette doesn't get on the helicopter but instead heads home to confront Nick, for what reason we don't know. During their fight, Trubel conveniently shows up with tranquilized arrows. Not long after mysterious figures burst into Nick's house, abduct Juliette and Trubel, and clean his house, leaving no trace. Someone was watching Juliette and the only way they'd be watching Juliette is if someone else talked. I think she was betrayed.

The best way to frustrate a cyberbully is to ignore him.
