How prevalent is online abuse?
Rape threats made to feminist campaigner and freelance journalist Caroline Criado-Perez on Twitter have sparked a heated debate about the criminality of online abuse and a company's responsibility to tackle it.
The threats, which came after Criado-Perez ran a successful campaign to get a woman on a bank note, are the latest in a long line of online abuse cases to gain widespread attention.
The subsequent debate has focused on how much Twitter and other companies should do to tackle abuse of their users by other users.
There are three main camps, loosely 'do regulate', 'don't regulate' and 'can't regulate'. Some of the arguments are ideological, but others centre on whether it's feasible or not to regulate or moderate billions of messages.
While anecdotal evidence of horrific threats abound, there's little data on how common occurrences of abuse are and how widespread the problem is. We've tried to look at what's available to help inform the debate.
