FiremanBill probed me at several planets today. That tends to get my attention, so I phalanxed his home planet and see he has a bunch of activity including a hit on Lord_of_War, who must be offline. I probe Lord_of_War's target planet -- rez there and a few cargo ships, not much else. I messaged Lord_of_War about payback and continued to watch FiremanBill. After a while, he got quiet. Some time later, Lord_of_War messages me back -- has no fleet available, but has IPMs. Great! I probe FiremanBill's planet and launch my whole fleet except RIPs. I launch my IPMs in range. Lord_of_War and his friends launch IPMs. Most of FIremanBill's defenses go up in smoke. My fleet hits...

Seems the fireman couldnt prevent the fire on his fleets. Crashed and burned. Top hit and this is what happens when you make yourself a target.
