For the record, I'd watch that show religiously.
I'd put it on MTV, and I'd cast a group of fun, flirty social media mavens and pseudo-celebrities from Instagram and Vine as the main cast. Each episode, they'd comb the internet (or take viewer nominations) for the most heinous internet trolls, and they'd systematically build a case against them tweet by tweet, comment by comment. After the investigation, just like on Catfish, the team would track down the troll and ambush them with every single offensive thing they've posted online.
Can you imagine Twitter during these episodes? It would be insane!
Then, after a commercial break, the troll would agree to a social media Intervention, where they have to sit and have dinner with people (or groups) that they've disparaged online, and hear how their words effected them. Obviously, some trolls would freak out and not apologize (while others would probably cry for the camera) but, in either case, it'd be great television.
I'd call it -- Feeding the Trolls
