Came across this article in yesterdays newspaper, apparently a think tank at Sussex university catalogued over 130,000 messages on Twitter that used terms like "slut" and "whore" as well as rape threats and other comments typically associated with sexism and misogyny. Yet these comments where directed by women at other women almost as much as they where from men, if the study was expanded and verified the findings it has some interesting implications for the claims of the "purely male" hatred online".
