Kathy Sierra used to have a technology blog, Creating Passionate Users. In March 2007 she announced that she was cancelling her appearance at O'Reilly ETech. Sierra had been regularly criticised on websites including meankids.org on technical matters. At some point at least one anonymous poster escalated the criticism and expressed their desire for Sierra's death, together with an image of her with a noose. The same poster had made violent sexual suggestions about her. Sierra explained that the threats had terrified her.
