Mr. Jones gets in a dispute with Mr. Smith. Mr. Jones, in a huff, searches the leaked bar database to see what he finds. He goes around the neighborhood telling everyone Mr. Smith used to hang out at gay bars, or that Mr. Smith habitually bar hops on weekends, or that Mrs. Smith emasculates her husband by going to the bar with her friends while he stays home with Smith Jr. Mr. Smith loses some business opportunities, or gets in hot water with his religious relatives, or just notices people laughing at him behind his back at the block party. If Mr. Violent Bigot is his next door neighbor, maybe this is how he learns Mr. Smith is gay, or hangs out at bars frequented by other races, or whatever. Also, stalkers could easily use this to track their victims and people who they associate with.
