Oldest memory that sticks out is my science blaster with hover, flying over Perez Park and sniping groups of skulls and Hellions into chasing me towards other players. If the player ignored the gang, they'd be fine, if they attacked, they'd generate threat and the whole gang would attack them. This was in the first few weeks of the game before griefing and etiquette were sorted out and Perez Park was were everyone went. Years later, it became a ghost zone, no one ever went there.
