Agree, I never actually met anyone of the 13th apparently (pity you, I was in a shieldless T-9, an interdiction magnet

), but I've been far more threatened by NPCs' than by actual cmdrs. The only one that managed to deprive me of 6.5 millions for a new freighter (plus cargo) has been a random guy ramming people at the mailslot, and only because after many wasted rebuys he succeeded in catching me off guard and a bit overspeed (still the lamest way of playing imho, but shame on me for falling for it). The only other rebuy happened because of a NPC Clipper that I clearly underestimated. Apart from this, a couple of close calls due to NPC interdictions but no blockade to be seen.
Also, hat off to the one cmdr in a Cutter who actually interdicted and pirated me the way it should be done, never happened to me before, kudos for the clean work.
I'll gladly take the risk of meeting pirates and blockades in an unshielded helpless ship any day over boring rinse-and-repeat hauling work

(of course preferably *
after* having secured my financial position with the right amount of solo rinse-and-repeat hauling work

)
