The face of scum.
1 person.
137+ lives shattered.
Sick twisted perversions.
>Geophysicist Dr Matthew Falder, 28, lead a secret double life during years of study at Cambridge University, where he was known as a fun party-goer.
He used many false identities to befriend more than 50 victims on internet marketplace sites such as Gumtree.
Falder - who pleaded guilty to 137 charges at Birmingham Crown Court on Monday - persuaded them to send him naked or partially clothed pictures of themselves, then threatened them with exposure unless they went much further.
He shared many of the images in sex abuse forums on the hidden dark web where he used identities including '666devil' and 'evil mind'.
He targeted his victims for at least eight years and was unmasked only after detectives brought in specialists from GCHQ, the Government's communications spy centre.
His victims were girls, boys, women and men. Some were so traumatised they self-harmed, or attempted suicide.
