What it needs to do is that people who obviously bully someone, like that crap that happened today, needs to take a vacation.
Like have their names lit up in pink, making that comment thing under their name and their signature state that they are bullies. For a month or two.
If it's repeated a lot it should lead to a permanent ban.
Sure, most of it comes from some people being insecure about themselves and thus having to oppress others in order to feel big... So they have their problems.
But they need to know it's not okay to do that shit, still. They won't grow up and solve their own predicaments unless they have to.
