The players are the ones that are forcing you into this and costing you 2k not BW. Also hard to foresee everything that a player would do to just agravate others.
Now knowing this maybe BW should put in the game were someone infected cannot get on fleet or off the planet until they are cured. Something along the lines "Due to the rampant spread of the infection all ports leading off the planet are closed until you are clean of this infection".
Are you naive? If there is a way to grief others, players will do it. This si why MMOs have to have events with training wheels because players will almost always seek to grief others.
