Perhaps Twitter should consider looking at verified accounts in a completely different way... maybe it should be a compulsory part of signing up for an account. If you've handed over government issued identification papers during sign-up (driving license, passport etc) to prove who you are, you're significantly less likely to start sending out death threats - unless you're stupid.
Criticism is great and without it there'd be a lot less motivation for humans to push themselves and keep coming up with better films, better ways of farming, better cars and better air travel, but empty, meaningless remarks don't help anyone. And if the authors of such remarks are being honest, it doesn't help them either.
I love animals. I really do. I'm a sucker for every cute kitten video and baby hedgehog GIF on the internet. Although I myself am not vegetarian, I barely eat meat and come from a family of vegetarians. I am staunchly against cosmetic animal testing, battery farming, and cruelty to animals in general. And yet despite this, I am also vehemently against PETA.
Clearly we as society, policymakers and website service providers need to consider how we can do more to ensure less people become victims of online abuse, commit suicide, have "bad internet experiences," are forced to move from school to school, home to home, and are even afraid to use the internet.
