I got mugged in Fujin. Launched about 50 mines at him...
Then when i was down to 49% hull gave him 5 of my rares and he let me go.
So the mines were no use then? I've wondered about trying them.
I also got mugged in Fujin last night, and again by a different CMDR at the next stop Wolf 1301. Fortunately both were genuine pirates. My evasion plan went completely to pieces under pressure. I lost the interdiction, forgot to chaff (is there a way to tell whether he's using gimballed weapons?), forgot shield cells until too late. A misunderstanding with my key-macros meant that I stopped boosting.
At 30% hull and shields gone the HUD said "Missiles". Then something like "Foreign body has attached to the ship" - presumably limpets. Fortunately my FSD finally finished its very slow charge and jumped and I don't think I lost any cargo. He could have easily destroyed me if he'd wanted.
I usually try to escape from pirates rather than give cargo. It's more exciting. But then sometimes I load some more valuable cargo (the locally bought rares aren't worth much unless you travel far to sell them), fly back to get interdicted again and make a donation, Charity to pirates? They wouldn't like to think so.
