This is happening in 0.5 security space and above:
An individual sits within range of a station, and targets capsules and shuttles as they exit the station, using a Thrasher. Since this individual knows they are going to get killed by Concord, they simply refit another ship within a few minutes and rinse/repeat, and apparently make enough from the loot (this is at a major trade station) that they do not care about losing their ship.
This individual is in a player-owned corporation with only two members, so I will presume it’s one-man corp. Since this individual has been doing this repeatedly, the cost of losing their ship is bearable to them…so as long as they are sitting near the trade station doing this, what recourse is there that will hurt them? Since they are getting killed by Concord repeatedly, if I attack them it will just be another inconsequential ship lose to them.
