It does go away, nobody remembers Boxxy/Katie of youtube/4chan fame? The horde went after her worse than threats and calls yet she's still there making vids. She didn't write a big victim blog or appear on Oprah (Jessi Slaughter) and the lynch mob quickly lost interest when denied their reaction prize.

Threats of course should be handled by police and not ignored, but the moment you seek media attention or acknowledge how the horde has "ruined your life" you are throwing gasoline on the fire.
