Can't say I'm behind the approach but it might help loosen the stranglehold that social media has on average people's lives. I'd agree that anonymity enables greater levels of toxicity, but I think a greater problem is credibility. Its almost impossible on the internet today to know who is 'credible' and if we solved that problem a lot of the toxic content and misinformation would fall into the 'not credible' arena and we could treat like fringe fiction accordingly.
