How does this movie have any sort of anti-cyber bullying message?

I've see a lot of interviews of the cast members claiming that the movie is relevant to cyber-bullying. I just watched spoiler videos for movie, and now I'm terrified for basically kids under 15 who actually thinking that the deaths were justified. Like wtf? There is nothing about this movie that realistically responds to cyber-bullying.

Two contradictions to it's message

1) None of these deaths teach us anything about cyber bullying. Even Ken who did nothing to Laura is killed off by the ghost.

-TBH I don't think the "cyber" part of cyber-bullying is the greatest issue. Kids just need to respect each other and ignore petty insults. If it's cyber-extortation or a legitimate physical threat,call the police.

2) The film would've been alright if the ghost was just another ghost who wanted to screw around or if it was just a serial killer. It defeats the purpose of horror movies trying to make the "bad guy" the "good guy" or to justify their motives. Horror always just refers to evil at hand. The real horror is kids under 15 thinking this is realistic.
