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. Once a cultist talked her way into working in Singer's campus office, then stole a sheaf of term papers and sent bizarre notes to the students.
But not everyone agreed with her views on the subject, and Singer paid a price for her work. Cult "operatives" dug through her trash, went through her mail, picketed her lectures and sent her death threats. They also hacked into her computer countless times, once released dozens of live rats in her house, and frequently left dead rats on her doorstep with threatening notes.
