One of the things that I hope for would be to have the formalized online peer support and online counselling offered more regularly in the hours that this happens to young people. You could be waking up in the middle of the night to 40 tweets telling you that you're ugly and that you should die. We need more services that would be able to respond to those needs, so that you know you're going to go to someone who is accountable for what they say to you.
The other thing I would add is that I had a very good friend who was in and out of the hospital for abuse she was receiving on Instagram and Twitter. Every time she'd go in the hospital they'd take her phone away. Of course she is going to get better if her phone is not there, and so they weren't addressing the issue. Then she would get back out, see what everyone was saying about her, and then go back in. It was a merciless cycle.
I would encourage more evidence-based and better services to be available online. There's an organization out of the United States where young women who have been harassed can get online support from other young women who have been harassed online. I found it really helpful, and so did a lot of my friends, just to be with people who know what it's like to be hit with a constant barrage of seeing awful things about yourself everywhere.
