Over the decades, cult operatives have fished through Singer's trash, sent her death threats and picketed her lectures. They've released dozens of live rats at her house, put dead ones on her doorstep (hearts skewered with lollipop sticks) and hacked into her computer so many times she doesn't use one any more.
