This is a disturbing video and I don't agree with Ruben's solution's of trolling. Even if there is a successful campaign to fuck with the degenerates they will just adjust and/or accept that there's people fucking with them. Look at all the
Predator Catcher Community, you already have vigilantes on chat sites stinging pedos constantly. Child molesters already know full well that they have to not only fear the wrath of the police but there can also be just some angry dude with a camera ready to film them at Walmart and put the video up online for their humiliation. Does this actually stop them? Hell no.
What needs to be done is that children need to be kicked out of all multiplayer games where they can potentially get targeted by perverts. If a game detects a high pitched child's voice it needs to be muted. A game like Roblox which heavily attracts children needs to be limited as Disney's Toontown, they should only be able to communicate with emotes and simple prewritten words. I don't give a damn that kids love the game because they play and talk with their friends, they're children they should not be fucking with the computer for hours at a time anyway.
