Most secrets don't seem like they could "ruin" anyone's life, either. I mean, people aren't admitting to crimes here. They could also claim to be trolling if anyone "caught" them. It seems a bit overdramatic.

Now, some of the non-secrets, the troll comment...yeah...maybe. But still, that seems highly, highly unlikely. It's not like trolls are generally caught and shamed, no matter how nasty the are.
