Gossip

If I had a triple filter I probably wouldn't talk near as much. When most people gossip they aren't even aware of it. They see it as just talking with friends not as hurting someone. It would keep me from hurting a lot of other people.
If you know what it feels like to be gossiped about why would we do it to someone else. Mostly its because of popularity. Some people don't even see it as gossip they're just talking. Another reason is because they want to fit in with the crowd which isn't always the right thing to do.
