There’s a difference, though, between everyone having access to what you have done, and people in your circle of trust gossiping about you to people outside of it. First, you can theoretically figure out the gossip and exclude them. Second, the gossip gossips about things _they_ find interesting, not about things random bored trolls find juicy. Thus, the odds of your faux pas exposing you to abuse are naturally lower.

In other words, “small towns have no secrets” is an oversimplification.
